As a rare metal, tantalum has relatively little resources on earth compared with other metals. The world's proven tantalum resources are mainly distributed in Australia and Brazil. Australia alone accounts for nearly 62% of global tantalum reserves, followed by It is Brazil, accounting for 36% of the total.
        According to the latest survey data released by the United States Geological Survey (USGS) in 2014, the world's identified tantalum reserves are 364,000 tons, and Australia, Canada, Brazil and African countries account for 85% of the world's tantalum resources. Among them, Australia has the highest tantalum reserves, ranking first in the world. Australia has 62,000 tons of tantalum reserves, and Brazil has about 36,000 tons. The United States, Burundi, Canada, Congo (DRC), Ethiopia, Mozambique, Nigeria, and Rwanda all have tantalum resources distributed, but the exact amount is uncertain. Among them, the resources of proven tantalum deposits in the United States are about 1,500 tons, but according to the market price of tantalum in 2013, these resources have no economic mining value.
        The world's proven reserves of niobium resources are about 11.5 million tons. Among the known deposits, the niobium content is about 19.8 million tons. Brazil has the largest niobium reserves, accounting for 91.1% of the world's niobium reserves. Brazil's CBMM, Catalao and Canada's Naobek are the world's major suppliers of niobium ore and niobium products.
         The reserves and distribution of tantalum resources in my country:
         According to the statistics of China's ore reserves in 2007, my country's tantalum minerals are distributed in 92 mining areas in 13 provinces (autonomous regions), and the total reserve of Ta2O5 is 84,000 tons. and Guangdong a little time. These three provinces (autonomous regions) account for 72.5% of my country's total tantalum reserves. The total amount of Nb2O5 in my country is 3.88 million tons, second only to Brazil and second in the world. The industrial reserves of niobium in my country are about 6.6 million tons, and there are 99 mining areas dominated by niobium. The distribution of tantalum ore resources in my country is as follows: Jiangxi accounted for 25.8%, Inner Mongolia accounted for 24.2%, Guangdong accounted for 22.6%, the three provinces (regions) accounted for 72.6%, followed by Hunan accounted for 8.6%, Guangxi accounted for 5.9%, Sichuan accounted for 5.3%, Fujian accounted for 5.3% It accounted for 5.1%, Hubei accounted for 1.2%, the five provinces accounted for 26.1%, and the five provinces (regions) including Xinjiang, Henan, Liaoning, Heilongjiang and Shandong accounted for 1.3%. Placer reserves: tantalite minerals are mainly distributed in Guangdong, and fine spar minerals are distributed in Hunan and Guangdong, with the former accounting for 55.5% and the latter accounting for 44.4%.
