Artisanal and small-scale miners also played a significant role in the country's cobalt and gold mine production (Bedidjo, 2018, p. 9; Matthysen and others, 2019a; Republique

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).

Considering the fact that this is regarding as small-scale mining, its contribution to the social and economic development of the region is much bigger. Small-scale mining generates significant local purchasing power and leads to demands for goods and services, such as tools, equipment, food, infrastructure, and housing (see Fig. 10.5).

The majority of mineral extraction in Burundi is carried out by artisanal and small-scale mining. Tin, tantalum, tungsten and gold are the primary minerals mined and exported. This report provides a view of the importance of these minerals and the ASM sector to Burundi's economy, associated taxation and revenue challenges, and …

Most of the current tantalum production originates in the Great Lake Region in Africa (Rwanda, DRC and Burundi).

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. ...
