Key Points
-
Rare earths testwork in Johannesburg strengthens Africa’s role.
-
Global rare earths advance sparks renewed investor interest.
-
Strategic supply chains hinge on rare earths innovation.
South Africa is becoming more important in the global rare earths conversation after new rounds of testing in a metallurgical lab in Johannesburg showed promising results. China still controls the majority of the industry, but Western governments are increasingly looking for other sources of supply. This development makes Africa’s growing role in critical minerals even more important.
The study, which took place at Mintek’s Johannesburg facility, focused on improving methods for separating and recovering rare earths. Mintek is South Africa’s state-owned mineral research organization. People who know about the testwork say that early results show that processing ores is more efficient, which could lower costs and environmental impact.
The Johannesburg rare earths testwork looks good
Companies like Rainbow Rare Earths Ltd., which is working on the Phalaborwa rare earths project in South Africa, and Frontier Rare Earths Ltd., which is based in Johannesburg and has exploration assets, see the results as important. Both companies depend on advanced processing a lot to make their deposits profitable.
According to a report by Mining weekly, George Bennett, CEO of Rainbow Rare Earths, said, “Every small gain in the lab is important in the field.” “What we’re seeing in Johannesburg shows that Africa can do more than just extract resources; it can also add real value through technology.”
South Africa has a long history of mining and is using that knowledge to get into the rare earths market. Analysts say that the testwork makes the case for turning African deposits into reliable supply alternatives stronger, especially as demand around the world rises.
Investors are interested in global rare earths advances
The most recent rise in rare earths prices in Johannesburg has caught the attention of financial markets. After hearing about Mintek’s progress, junior miners in southern Africa said they had more interest from investors. Even small improvements in lab performance are important to funders, who often have trouble getting money for their projects.
Rare earths are very important for clean energy technologies. They power everything from the motors in electric cars to the magnets in wind turbines. They are also very important for telecommunications and defense systems. With demand expected to rise by more than 40% by 2030, investors are keeping a close eye on Africa to see if it can help make up for China’s 60% production dominance.
The strategic race for rare earths is getting more intense
South Africa’s progress is a direct result of the strategic competition that is currently taking place in global supply chains. The US Geological Survey (USGS) has worked with African governments to map mineral resources. The European Union recently added rare earths to its list of “critical raw materials.”
Johannesburg’s testwork adds to these moves, showing that Africa is no longer happy to just send raw ores to other countries. Thabo Mokoena, Director-General of South Africa’s Department of Mineral Resources and Energy, said, “If these lab breakthroughs can be scaled, South Africa could become a hub for rare earths processing.”
The rewards for businesses like Rainbow Rare Earths could be huge. The Phalaborwa project in Limpopo Province is being planned as a processing-first operation, which means it will skip traditional mining and instead reprocess gypsum stacks that are rich in rare earths. The success of these kinds of projects may depend on the very improvements that are being tested in Johannesburg right now.
The symbolism is clear, even though it’s still early: Africa is moving up the value chain in important minerals, and investors around the world are paying attention.
