Coltan is the industrial name for columbite–tantalite, a dull black metallic ore from which the elements niobium (formerly "columbium") and tantalum are extracted.
The niobium-dominant mineral is columbite, hence the "col" half of the term. The mineral concentrates dominated by tantalum are referred to as tantalite.
Tantalum from coltan is used in consumer electronics products such as cell phones, DVD players, video game systems and computers. Export of coltan from the eastern Democratic Republic of the Congo to European and American markets has been cited by experts was helping to finance the fomer-days conflict in the Congo, “especially in the Democratic Republic of the Congo, is directly connected to coltan profits” An estimated 6.9 million people have died since 1998 in the war in Congo.
The Rwandan occupation in the east of the Democratic Republic of Congo (DRC) was a key factor preventing the DRC from exploiting its coltan reserves for its own benefit. Mining of the mineral is almost exclusively artisanal and small-scale.
Note that the amount of coltan produced in Congo is a fraction of what is produced worldwide. A 2003 UN Security Council report charged that a great deal of the ore is mined illegally and smuggled over the country's eastern borders by militias from neighboring Uganda, Burundi and Rwanda. Coltan smuggling has also been implicated as a major source of income for the military occupation of Congo.
Most people states that the search for coltan was fueled a brutal conflict in the Democratic Republic of Congo; they state that demand for coltan has caused Rwandan military groups and western mining companies to seek hundreds of millions of dollars worth of the rare metal, often by forcing prisoners-of-war and even children to work in the country's coltan mines.
As the peace has come Boss Mines Group has come to prevent the Tantite (Coltan) smuggling in the eastern part of the Democratic Republic of Congo (Zaire) especially Durba region in particularly. Our Companies has capacity of producing about 3-5 tons of 30-35% per weekly.
