According to the U.S. geological survey (USGS) data released in 2015, global tantalum resource reserves of more than 100000 tons, including Australia, 67000 tons, about 36000 tons of Brazil. The United States, Burundi, Canada, republic of the Congo (gold), Ethiopia, mozambique, Nigeria and Rwanda have tantalum resource distribution, but the specific number is uncertain. In addition, according to media reports in China, in 2014 and 2015, respectively, in China (300000 tons) of tantalum niobium resources in shaanxi province and jiangxi (30000 tons) found oversize tantalum niobium resources, but the mineral flotation data may not be USGS statistics or indicators, we need to distinguish. Chinese tantalum mineral resources distribution in 13 provinces and regions, in the order: Jiang Xizhan 25.8%, 24.2% in Inner Mongolia, guangdong (22.6%), three provinces combined accounted for 72.6%, followed by hunan accounted for 8.6%, guangxi accounted for 5.9%, accounted for 5.3% in sichuan, fujian (5.1%), hubei accounted for 1.2%, five provinces combined accounted for 26.1%, and xinjiang, henan, liaoning, heilongjiang, shandong provinces combined accounted for 1.3%.


Placer deposits: tantalum ore minerals are mainly distributed in guangdong, microlite mineral distribution in hunan and guangdong provinces, the former accounted for 55.5%, which accounted for 44.4%, according to data released USGS2015 years global tantalum ore output in 2014 a total of 1200 tons, 30 tons more than in 2013. Major producer: Rwanda, Brazil and Congo (gold), mozambique. Among them, the output of Rwanda accounted for gold cil machine half of global output. Coltan (Coltan), Africa's spoken language of this composite mineral columbite - tantalite. Coltan is a kind of metal containing niobium and tantalum. Contain tantalum concentrate generally refers to the "tantalite". Viewed from the outside, coltan is a dark minerals. It is important to note that the export of coltan is one of the trigger of the Congolese war, a conflict that the death toll as high as 4 million. At present, Rwanda and Uganda by the democratic republic of the Congo to steal coltan, then exported to western (mainly American). Coltan is widely used in the manufacture of high-tech products, such as: mobile phones, DVD players, PS2, etc.


Tantalum metal mainly in Australia, one of the largest manufacturers of Sons of two tantalite Gwalia in the local development. Tantalum ore in Canada, Brazil, China and the democratic republic of the Congo (accounted for 80% of the known world reserves) has developed. Tantalum in Thailand and Malaysia have production, but only as tin coltan ore processing and refining by-products of associated products. The world has found Portable gold trommel that the main ore belt is located in the eastern democratic republic of Congo. In Ethiopia, mozambique, namibia, South Africa, Nigeria, Zimbabwe and Egypt also have found that sometimes there are some production. Mainly for the production of capacitor tantalum, is very important electronic components in electronic equipment, widely used in everything from mobile phones to laptops in electronic equipment. In the past decade, with a surge in demand and output electronic technology products, tantalum demand and prices soared. Price promotion aggravated the contradiction between the producers, especially the Congo and Rwanda.
