Tantalum supply from artisanal and small-scale mining: A

Research performed on the efficiency of artisanal processing at two coltan-cassiterite mines in Rwanda shows the occurrence of both very low and very high tantalum recovery rates (13% and 78%, respectively).Coltan is used primarily for the production of tantalum capacitors, used in mobile phones and almost every kind of electronic device. Niobium and tantalum have a wide range of uses, including refractive lenses for glasses, cameras, phones and printers. They are also used in semiconductor circuits, and capacitors for small electronic devices such as hearing aids, pacemakers, and MP3 players, as well as in computer hard drives, automobile electronics, and surface acoustic wave (Coltan

Coltan

Coltan. A piece of columbite–tantalite, size 6.0 × 2.5 × 2.1 cm. Coltan (short for columbite–tantalites and known industrially as tantalite) is a dull black metallic ore from which the elements niobium and tantalum are extracted. The niobium-dominant mineral in coltan is columbite (after niobium's original American name columbium ), andTCEs are already so diversified in their uses and widespread — having many divergent environmental, economic and social impacts due to extraction, processing and waste disposal — that expertsClimate-positive, high-tech metals are polluting Earth, but

Tantalum supply from artisanal and small-scale mining: A mineral

To this end, we evaluate coltan resources and ore bodies, grades and processing features, as well as recent production and export developments in the DRC and Rwanda. Based on these findings, we then discuss mineral economic implications that are relevant to consider for artisanal coltan supply on the background of local and However coltan refining and processing requires relatively sophisticated technology and there is no reported evidence of black market refining or processing so it may be assumed that the omission of the black market in refining is not a major shortcoming in this study.GLOBAL SUPPLY CHAINS OF COLTAN: A HYBRID LCA STUDY
