Tantalite is the tantalum-rich member, and Columbite is the niobium-rich member. Tantalite is named after its tantalum content, and, together with Columbite, are the most important minerals containing the rare element tantalum. The name Tantalite has been discredited by the IMA, with the more specific designations of Tantalite- (Fe) (also known ...

Columbite group minerals (CGM) are the main source for the production of niobium and tantalum metals. ... These experiments were complemented with isothermal roasting tests of the mixtures in air ...

The increased demand of metals such as tantalum (Ta) and niobium (Nb) reflect the on-going development in modern science, engineering and technology. The extraction of these two metals from columbite-tantalite ore is based on generic extractive metallurgy. However, the upstream purification of ore and downstream extraction of Ta …

Below an average particle size of 100 microns, mechanical classification methods are difficult and the use of air classification is required. Modern air classifiers …

Centrifugal Classifiers Gravitational Industrial Classifiers These units employ centrifugal forces, similar to cyclones, to separate particles at cut points between 20 and 100 microns. A series of internal baffles apply drag forces to the coarse particles while allowing air to pass through them, resulting in separation of the fines.
