Columbite, also called niobite, niobite-tantalite and columbate [(Fe, Mn)(Nb, Ta)2O6], is a black mineral group that is an ore of niobium and tantalum. It has a submetallic luster and a high density and is a niobate of iron and manganese, containing tantalate of iron. This mineral group was first found in Haddam, USA. It forms a series with the tantalum-dominant analogue ferrotantalite and one with the manganese-dominant analogue manganocolumbite. The iron-rich member of the columbite group is ferrocolumbite. Some tin and tungsten may be present in the mineral.

Columbite Mineral Dressing Process - Powder Grinding :

After columbite ore stone comes out of the ground, it typically goes on a conveyor belt to a preparation washing machine located at the mining site. Then stone were crushed into small ones with crushers. The result materials will be put into the grinding mills. The grinding wheel acts like many hundreds of very small lathe bit, each cutting off some metal. Grinding abrades material in a way similar to sanding. After seprated and collected, we finally get the fine powder. We can smelt these columbite mineral powder for iron metal and byproducts.
