Mining production and recycling of 3TGS. Extraction of the 3TGs is widespread and includes primary large-scale industrial mining (LSM), artisanal mining and small-scale (ASM) mining as well as recycling. Most of the current tantalum production originates in the Great Lake Region in Africa (Rwanda, DRC and Burundi).

The global significance of artisanal and small-scale mining of certain mineral commodities implies the need for evaluating this production component as a potential long-term source of supply, in conjunction with production from industrial mining operations. The tantalum sector is an important pioneer in this regard, as artisanal 'coltan' ore - mainly extracted in …

This project focuses on artisanal and small-scale mining (ASM) of minerals and gemstones globally and the illegal mining and transport of these natural resources. Project scientists employ field mapping, geomorphological techniques, and remote sensing to map, monitor, and evaluate mineral deposits and ASM activities in conflict zones and …

Both mines ceased tantalum production in the late 2000's, which provided an opportunity for small scale artisanal production from Rwanda, and the Democratic Republic of Congo to fill the supply gap. Throughout much of the 2010's, 40% of the world's tantalum came from the DRC, and 18% from Rwanda and Burundi. ...
