This chapter discusses flotation and beneficiation of tantalum/ niobium ores. There is very little information or literature on flotation properties of tantalum minerals. Also, there are only a few operating plants that treat tantalum ore by flotation. Most of the commercial plants use a gravity beneficiation method.Web

The process of mining tantalum involves blasting, crushing and transporting the resulting ore to begin the process of freeing the tantalum. The ore is then concentrated at or near the mine site, to increase the percentage (by weight) of tantalum oxide and niobium. The material is concentrated through wet gravity techniques, gravity ...Web
