Beneficiation Process, Method, and Equipment for Tantalum-niobium Ore1. Brief introduction of tantalum-niobium minetantalum-niobium ore concentrateTantalum-niobium ore refers to the general name of minerals containing tantalum and niobium, and there are more than one hundred species. The tantalum-niobium ore that can be used for ore mining mainly consists of tantalite, columbite, and pyrochlore. Tantalite contains more tantalum called tantalite and contains more niobium called columbite. The following picture shows the original tantalum-niobium ore mining site in a country in Africa:the-original-tantalum-niobium-ore-mining-site-in-a-country-in-Africa2. Beneficiation technology of tantalum-niobium oreThe beneficiation method of tantalum-niobium ore needs to be determined according to the nature and structure of the ore. Under normal circumstances, we divide tantalum-niobium ore into two types according to the difficulty of beneficiation, one is tantalum-niobium ore with complex structure and composition, and the other is tantalum-niobium ore with single structure and composition. Tantalum-niobium ore in China and tantalum-niobium ore in Africa are just the representatives of these two tantalum-niobium ores.Tantalum-Niobium-Ore-Beneficiation-Plant-in-Mozambique3 China’s tantalum-niobium ore beneficiation technologyThe grade of tantalum-niobium ore in China is generally very low, the ore is relatively brittle, and the density is high. Generally, the process of staged grinding and staged beneficiation is adopted. The tantalum-niobium mine in Yichun, Jiangxi, China adopts the process of staged grinding and staged gravity beneficiation for beneficiation. Finally, a concentrate containing 14.94% tantalum and niobium was obtained, and the recovery rate was 75%.An ore body in Dajishan, Jiangxi, China is a large granite ore body containing tantalum, niobium, and tungsten. The main minerals include wolframite, scheelite, tantalite, etc. Since the particle size of the useful minerals in this mineral is very fine, if only a single gravity beneficiation method is used, the recovery rate is very low, so it is necessary to increase the flotation process.Tantalum-Niobium-Ore-Beneficiation-Plant-in-MozambiqueThe results of the concentrate obtained by the combined gravity beneficiation-flotation
