Nigeria Yet to Take Advantage of its Abundant Mineral Resources

0

A professor of Metallurgical and  Minerals Engineering at the Federal University of Technology Akure FUTA, John Ade Ajayi ,has lamented that Nigeria has been unable to utilize its  abundant mineral resources to create sustainable wealth and drive real  development that impact the people. Ade Ajayi made the submission while delivering the 146th Inaugural lecture of the Institution with the title: “Rich Nation, Poor People! The king of Metals as Paradigm: Quo Vadis Nigeria?” on the 10th of January 2023.

He said Nigeria is blessed with a lot of non-ferrous minerals including copper ores capable of contributing immensely to the Gross Domestic Product, GDP of the country. He however lamented that in spite of the abundant mineral resources there is hardly any serious actual mining capable of making Nigeria an industrialized nation. According to him,” There is no single functional and sustainable mine, mill or metal extraction plant in Nigeria. The National Iron Ore Mining Company, Itakpe, Mine and Mill are not really operational for now. The only tin smelting plant in Nigeria, Makeri Smelting Company, Jos has gone into the dustbin of history. What is prevalent is artisanal mining and ‘processing’ and quarrying. “He described the operations of artisanal miners as, “Unscientific, untechnical, uneconomical, unsafe, unhealthy and environmentally unfriendly.”

Professor Ade Ajayi   said there was an urgent need for government to lead the drive to chart a new direction for sustainable mineral resources development that will engender economic prosperity in Nigeria through correct policies. He said the economic development of any nation depends considerably on its level of industrial development and this in turn depends invariably on the level of mineral exploration and manufacturing activities in the national economy. He said concerted effort must thus be taken to revive industries and set factories working through minerals and metals value chain in Nigeria to improve the quality of life of its people.

He said the importance of iron and steel production in the national economy like Nigeria cannot be overemphasized as it is presently recognized that a nation that controls iron and steel controls the world. To this end he recommended that a Council for the Nigerian Institution of Mining and Metallurgy (CNIMM) be put in place in accordance with international best practices to see to the sustainable production of non-ferrous metals required for the production of ferro-alloys and different types of alloys.

Ade Ajayi , Nigeria’s first professor of metallurgical and minerals engineering , said in order to be able to sustainably produce mineral and metal products for the use of the society, the Nigerian mining, minerals and metals (3M) industries should have viable linkages with academic institutions and research institutes. He said the 3M industries are to produce goods and services for the society thereby generating employment, creating wealth and engendering national economic development. The Don called for a clearly convergent point between inventors and investments in Nigeria such as science and technology parks for startups.

He recommended that FUTA as the best university of technology in Nigeria should be declared as a centre of excellence in Mining engineering, mineral processing technology and extractive metallurgical engineering. According to him, there is the need to transform the Nigerian universities from the present intellectual amnesia to intellectual revolution.

Ade Ajayi advised that competence enhancement and training should become the hallmark of those driving the country’s policies saying, “The funds used for junketing and seeking international investors can be used for training and research. For national interest, we must reorder our priorities.”

The Vice Chancellor, Professor Adenike Oladiji, in her address said Professor Ade Ajayi has been a consistent productive scholar, a metallurgical engineering expert and an educational manager per excellence. She said Professor Ajayi had contributed significantly to knowledge in his chosen area of Metallurgical and minerals engineering.

Ethiopia: Akobo Minerals to Start Production After Three Months

0

Akobo Minerals, a Norway based gold exploration and mining company, will start production after three months. The company is expected to generate USD 100 million annually once it becomes fully operational.

The mining company focuses on projects along the Akobo river in southwestern Ethiopia. It received its first exploration license over 10 years ago which has now been converted into a mining license for part of the exploration license area. Akobo Minerals is led by a management team which is based in Norway and Sweden while its local team comprises of 40 Ethiopians.

Modern mineral exploration began in Ethiopia in the late 1890’s by foreign companies. Gambella, Benishangul Gumuz, Oromia, and South West Ethiopia are known for their gold resources. Gambella Regional State’s Akbobo narrow greenstone sub-belt is labeled a high potential target for gold exploration by the Ministry of Mines.

Ethiopia earned USD 560 million from gold during the 2021/2022 fiscal year.

Zambian President has Shown Interest in Importing Angolan Refined Oil

0

Zambia has agreed to buy a stake in Angola’s Lobito refinery in Benguela Province along the Atlantic Coast.

President Hakainde Hichilema, during his three-day visit to Angola, assured his host that his country would invest in the Lobito refinery that is under construction.

“It makes no sense to import fuel from other parts of the world when we have a neighbouring producer,”  Hichilema told journalists at a press conference in the capital Luanda after a meeting with President João Lourenço.

“I don’t know how we have managed to maintain this situation of buying fuel from Saudi Arabia and other parts of the world and not from our neighbour,” he added.

Hichilema arrived in Luanda on Tuesday and will visit the refinery in Benguela on Thursday, and the Lobito corridor, consisting of railroad and port, offering the shortest route linking Zambia and the Democratic Republic of Congo’s (DRC) key mining regions to the Atlantic Coast.

In July, the Angola government signed a 30-year concession with a consortium of Trafigura, Mota-Engil Engineering and Construction Africa, and Vecturis, Belgium, to operate rail services and offer logistical support for the Lobito corridor.

The rail line runs approximately 1290 kilometre from Luau on the eastern border with the DRC to the Lobito Port on the Atlantic.

Angola and Zambia are also conducting a feasibility study for a proposed oil pipeline from the Lobito refinery to Lusaka.

Lourenço said the refinery construction is expected to be concluded in 2026. “It is very natural that Zambia, as our neighbour, has a great interest in acquiring these fuels in Angola, in the neighbouring country, especially when Angola has a greater capacity to refine the crude oil it extracts,” Lourenço said.

The refinery is projected to process up to 200 000 barrels per day when completed. According to a proposed governance structure, private investors, including Zambia, will own 70%  of the refinery, with Angola state oil firm Sonangol controlling a 30% stake.

Working towards environmentally friendly lithium extraction methods

0

Lithium is a crucial component in the switch to renewable energy, but the extraction process of this critical mineral has been costly to the environment.

Lithium arguably plays the most important role in ditching fossil fuels and ensuring the world can move towards a zero-carbon future. The lightweight metal is found in rechargeable lithium-ion batteries, which are used in most personal electronics and most importantly, electric vehicles (EVs).

The demand for EVs has seen a huge increase in recent years, with companies scrambling to target multiple lithium exploration projects to ensure lithium supply can meet demand. However, in order to ensure the safety of our planet, lithium extraction methods must be done in an environmentally sensitive way that causes as little damage.

Any type of resource extraction is harmful to the planet, with removal of raw materials resulting in oil degradation, water shortages, biodiversity loss, damage to ecosystem functions, and an increase in global warming.

The Innovation Platform takes a look at why lithium extraction is bad for the environment and how companies are ensuring their extraction methods are eco-friendly so that we can meet the ever-growing demand for lithium.

The increasing demand for lithium

 Lithium demand is higher than ever, with calls for at least $42bn in lithium investment over the next six years in order to meet 2030’s goal of 2.4 million tonnes of lithium production per year.1

 The demand for lithium is so high due to its integral role in EV batteries. EVs are becoming increasingly common on our roads, with over two million vehicles sold in 2018 alone.

The growing interest in lithium has seen the world’s largest-known reserves increase significantly. According to the US Geological Survey, there are around 80 million tonnes of identified reserves globally.2

Lithium is irreplaceable for the high-energy batteries that power portable electronics and electric vehicles. It has a unique position on the periodic table, offering high voltage and high capacity that cannot be replicated by other metals. A select few battery technologies have shown potential to one day replace today’s lithium-ion batteries. These new batteries are based on lithium metal and lithium silicon anodes, which improve performance but also increase lithium usage per kilowatt-hour.

After South America – mainly Bolivia, Chile, and Argentina – the next biggest lithium-producing country is the US, followed closely by Australia and China. In 2019, lithium exports from Australia were reported to have totalled almost $1.6bn.

Lithium is mainly sourced from either spodumene or brine. Australia is home to the majority of hard rock (spodumene) mines, while brine production is concentrated in South America, mainly in Chile and Argentina.

Lithium carbonate and lithium hydroxide are the two lithium compounds employed for battery cathode production, with carbonate currently making up the bulk of usage. In brine production, lithium chloride is extracted from alkaline brine lakes before being converted to carbonate.

With this in mind, it is crucial to explore how these different extraction methods impact our planet and ecosystems.

Why is lithium extraction bad for the environment?

 Despite its potential to power a net-zero future, lithium extraction methods can cause great damage to the environment, with the metal often described as the non-renewable mineral that makes renewable energy possible. Extraction of the product causes several environmental defects, including water contamination and increasing carbon dioxide emissions.

Record results for Lynas as Malaysia decision looms

0

Lynas Rare Earths is set to appeal to the Malaysian Government today about unfavourable license conditions that threaten to interrupt its operations. But despite the impending battle, the company recorded strong results for the March quarter.

 

In terms of operations, the company called the results were “excellent”.

“Neodymium and praseodymium (NdPr) production of 1,725 tonnes was the highest ever quarterly production at the Lynas Malaysia plant,” the company told the market.

“This was achieved despite a general shutdown of the Lynas Malaysia plant for over 3 days whilst tie-in works for the mixed rare earth carbonate (MREC) receival facility were undertaken.

“The strong NdPr production result is the outcome of plant efficiency improvements and no significant downtime from external events.”

Lynas clocked in $237.1 million in quarterly sales revenue, up from $217.5 million in the previous quarter.

Closing cash and short term deposits counted over $1.1 billion.

The license conditions on the company’s Malaysian operations will prohibit the import and processing of lanthide, which will require the closure of the cracking and leaching component of the Lynas Malaysia plant.

Cracking and leaching leaves behind low-level radioactive waste, which the Malaysian Government seems no longer willing to tolerate.

Lynas has been racing to ramp up its Kalgoorlie rare earths processing facility to pick up the slack left by changes to its Malaysian operations.

“The Kalgoorlie… project has now entered the final phase of major construction activities and dry commissioning activities have commenced in certain parts of the plant,” the announcement said.

“We retain a target feed on date for the Kalgoorlie Facility in Q4 FY2023.”

When the expansion is complete, Lynas will undertake the cracking and leaching of rare earths in Kalgoorlie, before sending the intermediate product to Malaysia.

But the Kalgoorlie expansion won’t be on its feet until at least August, leaving a potential three-month void of rare earth supply.

Though the appeal will be heard today, there is no timeframe under Malaysian law by when the Minister is required to make a decision.

Investigations ongoing after death at Olympic Dam

0

A 25-year-old man has lost his life in the early hours of Anzac Day at BHP’s Olympic Dam mine in SA.  

 

According to South Australian police, the incident occurred around 5:30am on Tuesday. While the details of the accident remained undisclosed, it is believed that the man may have been struck by a vehicle at the mine site.    

Major Crash police arrived at the site and began an investigation.  

A BHP spokesperson said the company was working with authorities to determine how the incident occurred.  

“We are deeply saddened to confirm that a member of our workforce died this morning at our Olympic Dam site,” the spokesperson said.  

“The cause of death remains unclear. 

“Our thoughts are with the person’s family, friends and colleagues and we are offering all the support we can during this difficult time. 

“We are engaging with SafeWork South Australia and South Australia Police Service in relation to the incident.” 

Police are preparing a report for the coroner. 

Olympic Dam is a copper, uranium, silver and gold mine located roughly 560km north of Adelaide. It is one of the largest copper and uranium deposits in the world.  

Australia’s next uranium producer

0

Boss Energy’s Honeymoon uranium project is on track, with strong progress on all fronts.

 

The Honeymoon project is a uranium mine roughly 80km north-east of Broken Hill in South Australia. It ceased operation in 2013 due to low uranium prices and was bought by Boss Energy in 2015.

Approval for the revamping of Honeymoon was received in October 2022 and start-up is expected to occur in the December quarter of 2023.

Boss Energy hopes to produce 2.5 million pounds of uranium annually by 2026.

The company is fully funded through to production, with cash on hand of $103 million and a uranium stockpile with a value of $96 million.

Boss Energy also reported that $65 million, or 62 per cent, of budgeted expenditure has now been committed to the program.

The company also reported that all critical equipment components, including the essential ion exchange columns, are on track for delivery.

“All aspects of the construction are proceeding to plan, including delivery of critical equipment, wellfield development and the evaporation pond,” Boss Energy managing director Duncan Craib said.

“We are currently scheduled to be on track for first production as planned in the December quarter of this year.

“This timetable was designed to ensure we are in production at the start of the next forecast uranium bull market, not half-way through it.

“With the outlook for the uranium price continuing to strengthen amid growing use of nuclear power and a shift away from Russian uranium, we are perfectly positioned as we prepare to move into the final stages of construction ahead of commissioning.”

In January, Boss Energy appointed experienced mining professional James Davidson as the general manager of Honeymoon.

Davidson has previously held positions with Rio Tinto, Mt Gordon Copper and Energy Resources of Australia (ERA) at its Ranger uranium mine.

“James has immense experience across project management and construction, with a particular emphasis on uranium metallurgy and operations,” Craib said at the time.

“This knowledge will be invaluable as we advance development of Honeymoon and prepare for commissioning and steady-state production.”

Lynas launches appeal for Malaysia plant

0

The conditions of the license will prohibit the import and processing of lanthide which will require the closure of the cracking and leaching component of the Lynas Malaysia plant.

The appeal will be heard on April 28 by the Minister of the Ministry of Science, Technology and Innovation, 39 days before the conditions are set to come into effect.

But Lynas is concerned that the tight timeframe will cause a delay in its rare earths supply.

“There is no statutory time frame under the Atomic Energy Licence Act 1984 by when the Minister is required to make a decision on the appeals,” Lynas told the market.

“However, Lynas has requested that the appeals are addressed urgently.”

The company is further seeking a stay of the new license conditions until administrative and legal appeals have been resolved.

Lynas is racing to ramp up its Kalgoorlie rare earths processing facility to pick up the slack left by changes to its Malaysian operations.

“Planning for feed-on and production ramp up continues with a focus by the Lynas Kalgoorlie operational team on learning from the significant expertise of the Lynas Malaysia team in all aspects of cracking and leaching operations,” the company said.

When the expansion is complete, Lynas will undertake the cracking and leaching of rare earths in Kalgoorlie, before sending the intermediate product to Malaysia.

But the Kalgoorlie expansion won’t be on its feet until at least August, leaving a potential three-month void of rare earth supply.

Cracking and leaching leaves behind low-level radioactive waste, which the Malaysian Government seems no longer willing to tolerate.

TOMRA Mining technology to be installed in the Pilgangoora project

0

TOMRA Mining’s unique experience in the design and installation of large-scale ore sorting plants and its collaborative approach were the keys to the successful design of the world’s largest lithium sorting plant.

 

The installation has already started and is expected to reach completion in late 2023.

Pilbara Minerals owns the the world’s largest, independent hard-rock lithium mine. It is located in Western Australia and produces a spodumene and tantalite concentrate.

By pursuing a growth strategy to become a sustainable, low-cost lithium producer, the company has become a major player in the rapidly growing lithium supply chain. This investment will ensure the expansion of its large-scale operation in order to meet the increasing demand for lithium driven by sustainable energy technologies such as electric vehicles and energy storage.

“This new facility to be constructed at our Pilgangoora Project will be the world’s largest lithium mineral ore sorting plant,” Pilbara Minerals managing director and chief executive officer Dale Henderson said.

“TOMRA’s experience in large global sorting installations, innovative technology, and ability to provide local support were significant factors in our decision to work with them.

“From the start, the TOMRA team has been working side by side with us and our engineering partner DRA Global to deliver this important project.”

Processing contaminated ore: A key challenge for the lithium industry

As part of this expansion project, Pilbara Minerals turned to TOMRA Mining for assistance to address the key industry challenge in the processing of spodumene feed ore contaminated with barren host rock.

TOMRA has 50 years’ experience in sensor-based sorting technologies and has designed and built 90 per cent of the world’s large-scale mining sorting plants with a capacity above 300t/h.

These include plants such as the Ma’aden Umm Wu’al project, which is operating at 1850t/h, or the Lucara diamond operation which runs 15 sorters.

Specifically for the Pilbara Minerals project, TOMRA Mining offers effective ore sorting solutions with high sensor resolution and ejection accuracy that ensure high lithium recovery and waste removal with a stable and consistent performance at high capacity.

Valuable expertise and collaborative approach

The TOMRA Mining team conducted a geological assessment of sample ores supplied by Pilbara Minerals.

It revealed that the pegmatite deposit did have non-lithium bearing host rock intrusions. Some of these minerals have a high density like that of spodumene, which means that it is also concentrated when using Heavy Media Separation (HMS).

This reduces the efficiency of the downstream floatation and contaminates the final product. Sensor-based sorting technologies, on the other hand, can measure the colour, density, and mineralogical variations in individual particles, enabling the accurate detection and removal of this barren material.

Working closely with the Pilbara Minerals metallurgical team, TOMRA conducted extensive test work at the TOMRA Test Center in Sydney to check all the options and answer any questions arising during the tests.

The samples were run at capacity on production sorters and included repeatability and variation testing. The test work benchmarked the expected performance of the sorters and was used to establish the sort quality on each of the ore types that will be fed through the plant.

Primero Group, which was awarded the contract for construction of the project, has now started bulk earthworks for the sorting plant.

The TOMRA team was involved not only in the testing and supply of equipment, but also provided assistance with the plant layout and understanding of the implications of sorting on the upstream mining and downstream process of the ore.

This involvement throughout the development process will add to efficient operational ramp-up and technical optimisation.

Ongoing support with local team and global resources – de-risking adoption of a new technology

TOMRA’s capability to support the project with a dedicated Australian-based team and a global support structure has been a significant factor and is an important part of de-risking the installation of this new technology.

The team is working closely with Pilbara Minerals through the installation process, commissioning and start-up, and will continue to provide on-site support once the sorting plant is up and running.

Capricorn copper mine to reopen in 2024

0

29Metals’ Capricorn copper mine is still feeling the effects of unprecedented rainfall in Queensland, with the full reinstatement of the mine scheduled for 2024.

 

The company reported seven-metre flooding at the site in March following the extreme rainfall that struck the state.

The site suffered no significant harm to the processing plant, but supporting infrastructure was less fortunate with the company reporting some damage.

However, 29Metals has announced that there is still significant water on site, including approximately 500ml in the Esperanza South underground mine.

29Metals will undertake a phased approach to reinstate full mining capabilities at the site.

Initial reinstatement of operations, with a combination of ore mined from the Mammoth and Greenstone ore sources and stockpiles is planned to commence in the mid-September quarter of 2023.

Complete reinstatement, including the recommencement of mining at Esperanza South, will not be possible until the middle of the first quarter of 2024.

“Substantial effort has gone into ensuring that we properly understand the full impact of this unprecedented weather event and implement a responsible plan for the safe return to operations,” 29Metals managing director and chief executive officer Peter Albert said.

“With water levels on site now stabilised, the recovery task has become clearer. Water quality and reducing the additional water brought onto site by this event are the key enablers to recovery.

“I again want to acknowledge the efforts of the 29Metals team. The extraordinary work from our team on site to manage the impact during this extreme event – with no health or safety incidents, no uncontrolled releases of water from on-site water storage facilities and no loss of containment of tailings – is being matched by group-wide efforts to develop and evaluate recovery scenarios.”

The company is expected to finalise the recovery plan by mid-May and will update the market again once it has done so.
