Could Africa replace China as the world’s source of
Concerningly, production of these rare earth minerals has remained concentrated. China has a dominant hold on the market—with 60% of global production and 85% of processing capacity.Approximately 200 rare earth-bearing minerals are distributed in various mineral groups such as halides, carbonates, oxides, phosphates, silicates among others. Conversely, bastnaesite, allanite, monazite, ion-adsorption clays, and xenotime muds are the only minerals economically mined for the production of REEs.

Into Africa: the US’ drive for African rare earth minerals
Potential partners. The US has identified Malawi-based Mkango Resources as a means to diversify its source of rare earth minerals. Mkango owns and operates the Songwe Hill mine, which was revealed to have rare earth grades of up to 2.2% over 6.7m in drilling studies completed last year.

What are rare earth elements, and why are they important?
The rare earth elements (REE) are a set of seventeen metallic elements. These include the fifteen lanthanides on the periodic table plus scandium and yttrium. Rare earth elements are an essential part of many high-tech devices. The U.S. Geological Survey news release "Going Critical" explains:The rare earth mineral industry in Sierra Leone is touted as a new frontier with ongoing exploration and exploitation of “new deposits”. However, a review of Sierra Leone’s historical mining development reveals not only that knowledge of the occurrence of rare earth mineral deposits date back to the early 20th century when the British colonial The Sierra Leone rare earth minerals landscape: An old or

The Guardian view on rare earths: mining them can’t cost the Earth
A US Virginia-class submarine requires about four tonnes of rare earth materials. China has been willing to use key minerals as a political weapon. After tensions between Beijing and Tokyo boiledThe study was carried out to determine the rare metal mineralization potential of some pegmatites associated with metasediments in the Igangan 240 NW sheet. Geological mapping on a scale of 1:50,000 revealed the pegmatites intrude metasediments and geochemical analysis for major, trace and rare earth elements were carried out using ICP Rare Metals (Ta-Nb-Sn) Mineralization Potential of

Africa pushes back against China's predatory practices in rare earth
Africa is pushing back against China's predatory practices in the lucrative mining sector, particularly in the rare earth minerals sector. Resource rich bigger African states are pushing back against Beijing.

Pan-African rare metals bearing pegmatites in Wadi Ghadir,
Quartz-diorites, monzogranites and pegmatites are the main rock units in the studied area. The pegmatites occur as zoned pockets within monzogranites with zonal arrangement: border, wall, intermediate, and core zones. The wall zone have enrichment of radioactive and RREs-bearing minerals. K-feldspar, plagioclase and quartz are essential These geochemical characteristics are also displayed by the composition of eluvial heavy-mineral concentrates as well as by the trace-element distribution in cassiterites. Although Pan-African granites with an age range of 700-520 Ma are dispersed throughout Nigeria, associated rare-metal mineralized pegmatites are known almost exclusivelyNigerian rare‐metal pegmatites and their lithological framework

Rare Earth Element Deposits: Sources, and Exploration
Rare earth elements (REE) include the lanthanide series (La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu) plus Sc and Y. All these metals occur together in different types of REE deposits such as carbonatites, alkali syenites and monaziterich placers, and are found in more than 250 minerals in the Earth’s crust. The Africa hosts about 30% of the Earth's mineral resources and ranks first or second in the quantity of world reserves of platinum, chromite, diamond, bauxite, cobalt, manganese, zirconium and phosphate.(PDF) Overview of Nigeria's Mineral Resources in the
