(also known as "coltan") is a metallic
DOLV's soon to be formed Coltan Subsidiary - Definition: Columbite-tantalite
, (Fe,Mn)(Nb,Ta)2O6, or coltan, is a metallic ore found in Australia, Canada, Brazil, and central Africa.
The primary exploration focus of the Project is Neo-Proterozoic pegmatites mineralized with cassiterite and columbite-tantalite
(coltan); in addition to conventional geological, geochemical and geophysical exploration techniques that will be utilized the recently completed inventory of artisanal minesites will provide invaluable evidence of where the mineralized pegmatites outcrop and offer a weathered exposure amenable to primitive artisanal extraction.
The supply of columbite-tantalite
("coltan") from Central Africa, and specifically from the DRC, has been an issue of major concern for over a decade because of its association with the fighting between government troops and militias and attendant humanitarian crises in the DRC's Kivu provinces.
More accurately termed columbite-tantalite
, but universally known by its abbreviation 'coltan', author Michael Nest explodes many of the myths that have grown around this controversial metal.
According to the United States Geological Survey, Africa holds 90 percent of the world's deposits of cobalt, 90 percent of its platinum, 50 percent of its gold, 98 percent of its chromium, 64 percent of its manganese, 33 percent of its uranium, and 80 percent of its columbite-tantalite
The report also says that Apple is working with the Global e-Sustainability Initiative (GESI) and the Electronic Industry Citizenship Coalition (EICC) to ensure that their suppliers are using conflict-free sources of extractives, namely "The mining of columbite-tantalite
, cassiterite, wolframite, and gold which are refined into tantalum (Ta), tin (Sn), tungsten (W), and gold (Au), respectively [that] is believed to fuel political strife in the Democratic Republic of Congo and neighboring regions.
This was followed by accusations of gross human rights violation by Tutsi's dominated Rwandan Patriotic Front (RPF) and its allies in Eastern Democratic Republic of Congo (DCR) against native Congolese and dissident Hutus, and the pillage of DCR's resources in form of illegal mining of diamonds and Coltan (short for columbite-tantalite
, a metallic ore used in manufacture of components of mobile phones and consumer electronics products).
The law essentially bans the import of gold, columbite-tantalite
, cassiterite, wolframite, and their derivatives from the DRC by US-based publicly held companies, enacts strict reporting standards, and implements a new labeling procedure.
