The magnetic separator is used in a process to extract primarily tantalum from coltan, which is a combination of columbite and tantalite. For this new project, tests were undertaken in the Master Magnet test facility in Redditch, England. The tests confirmed the level of separation, capacity and the magnetic separator configuration.

Tantalum mining technique –blasting, crushing, transporting

Tantalite is the mineral ore containing tantalum. Most tantalum mines are open pit whereas some are underground. The mining process involves blasting, crushing and transporting the tantalite ore to start the process of separating tantalum. The ore is then concentrated at or near the mine site, to increase the weight of tantalum oxide and niobium after which the material is concentrated through wet gravity techniques along with electrostatic and electromagnetic processes.

Coltan Resources

Coltan is the industrial name for columbite-tantalite, a dull black metallic mineral from which the elements niobium (formerly "columbium") and tantalum are extracted. The niobium-dominant mineral is columbite, hence the "col" half of the term. The mineral concentrates dominated by tantalum are referred to as tantalite.
