Political instability, Congo mining area located in the eastern part of endangered species, the gorilla lowlands of the main habitats. Rwanda occupied in eastern Congo, the democratic republic of Congo mining resources in these
manganese beneficiation plant areas therefore failed to profit. A United Nations security council, the report said a lot of coltan ore processing in the eastern border countries, Burundi, Uganda and Rwanda militia illegal mining and smuggling. It is estimated that the rwandan army in less than 18 months, by selling coltan at least $250 million in revenues. This statement has been questioned, however, because Rwanda has its own tantalite, so hard to tell which is smuggling coltan ore processing.
Coltan smuggling also referred to as one of the main sources of income of the Congolese warlord. For many people, this leads to the similar ethical problems and conflict diamonds. Because is very difficult to distinguish between legal and illegal coltan, several electronic equipment maker decided to boycott all African coltan, switch to other coltan. The United Nations has charged the three countries smuggling coltan iron coltan ore processing bill eventually go away. The reference link below is a reporter Austria Klaus Werner records of multinational companies and coltan trading illegally. Also claims that
coltan ore processing mining coltan could seriously damage the local forest and wild animals, especially the survival of the gorilla, destroy the natural environment. Since Africa coltan ore prices rose sharply in 2000, after due. COM speculation and multiple orders, African mines produce of coltan iron coltan ore processing and niobium production dropped significantly. This has been the United States geological survey related survey data. Belgium of tantalum and niobium international study center (closely related to the country traditionally as Congo) has recommended that international sellers, from the moral Angle to avoid buying from the Congolese coltan:
"Democratic republic of the Congo, Rwanda and other African countries, in the past is the main source of tantalum coltan ore processing. Warlords, however, do not hesitate to undermine national park ecology, diamonds and other mineral resources
tin beneficiation plant and gain profit to the continuation of the civil war. This research center, called on members, shall carefully check tantalum coltan ore processing is derived from legal sources. For personal gain and harm to the locals, wildlife or the environment is not acceptable." Leaving aside the moral consideration, however, from a purely economic perspective, coltan ore processing supplier start from traditional areas such as Australia, transferred to the new location, such as Egypt. May by the world's largest suppliers, Australia's Sons of Gwalia co., LTD., caused by the bankruptcy, but the company still produce and export coltan ore processing.
