Coltan ore processing is rare metal, in the content of 0.0002%, in the earth's crust and niobium coexistence in nature. Contain coltan ore mineral processing a lot of, but as coltan ore processing mineral (Ta/Nb of 1) or more but not much, coltan ore processing of industrial value of main minerals are: coltan ore processing iron ore [(Fe, Mn) (Ta, Nb) 2 o6], coltan ore processing iron ore (FeTa2O6), microlite [(Na, Ca) Ta2O6 (O, OH, F)] and black thin gold [(Y, Ca, Ce, U, Th) (Nb, Ta, Ti) 2 o6], etc. The world's first, second big coltan ore processing ore were Wodgina and Greenbushes, are portable gold wash plant located in Australia. Our country's most famous coltan ore processing niobium for jiangxi yichun coltan ore processing ore, coltan oxide ore processing 18000 tons of reserves, niobium oxide reserves of 15000 tons. Our coltan ore processing mine, mainly of low grade hard rock ore grade in one over ten thousand, with about three over ten thousand of Australia coltan ore processing ore grade, production cost is higher. However, in 2015, jiangxi nonferrous geological prospecting bureau of mines can be detailed survey of hengfeng geyuan nb-ta mining coltan ore processing deposits, recognized by the ministry experts, Dartmouth large. The main mineral coltan ore processing through detailed investigation proved reserves of nearly 30000 tons, we'll double the prospective reserves. On January 16, 2014, shaanxi provincial geological survey institute said first discovered in eastern and southern shaanxi oversize niobium ore and rubidium coltan ore processing, including gold shaking table niobium coltan ore processing more than 300000 tons of resources, for our coltan ore processing mineral resources development with more resources.


Coltan ore processing mainly exist in the coltan ore processing iron ore, niobium and niobium iron ore coltan ore processing iron ore, but in addition to these sources, tin stone with such quality as exist coltan ore processing, it is important to coltan ore processing resources. Due to the separation method is difficult to coltan ore processing from tin stone, they enter the metallurgical slag in smelting tin. As coltan ore processing of mineral resources are dwindling and dilution, the tin slag coltan ore processing resources gradually became an important source of coltan ore processing raw material, 70 ~ 80 s of the 20th century increase of coltan ore processing raw materials by 70% ~ 80% of the total supply, still accounts for about 50% in the 90 s. From southwest China's guangxi, yunnan through myanmar, Indonesia, Thailand and Malaysia tin ore belt containing coltan ore processing is the most abundant, Thailand and Malaysia as coltan ore processing important supplier of raw magnetic separator machine materials. Tin contain coltan ore processing of niobium and containing coltan ore processing production of tin slag countries and countries such as Australia, Brazil, Bolivia, Nigeria. As coltan ore processing of mineral resources are dwindling, coltan ore processing increasingly shortage of raw material supply, secondary coltan ore processing of utilization of resources is more and more attention. The secondary coltan ore processing quantity of resource utilization of coltan ore processing raw materials by 10% ~ 20% of the total supply. Coltan ore processing as rare metals in the earth's resources more than other metals, is relatively small, the world's proven coltan ore processing resources are mainly distributed in Australia and Brazil, two countries enough reserves to meet expected demand. Australian country alone accounted for global coltan ore processing nearly as much as 62% of reserves, followed by Brazil, 36% of the total.
