Coltan Tantalum Mineral Coltan Grade 2 Containing Columbite And Tantalite Natural Tantalum Mineral Natural 100% Pure Co
Description:
Tantalite is produced in granite pegmatite, and it is often symbiosis with beryl, niobium yttrium, sodium flower, spodumene, phosporite, etc. The mineral contains 41%~84% tantalum pentoxide and 2.0%~40% niobium pentoxide. It is an important mineral for extracting tantalum and niobium. Pure tantalite is rare, and often has some niobium, which is a series with columbite, which is the other member of the mineral series. When pure, the specific gravity of tantalite is 7.9, which decreases as the niobium content increases.
Due to the high relative density of diamond and the low relative density of gangue associated with diamond, there is a certain specific gravity difference between them, so gravity beneficiation method can be used to recover diamond. The commonly used gravity processing equipment is the jig concentrator.
