Three Types Of Vanadium Ore Beneficiation Methods
The flotation of ilmenite is carried out in acidic pulp, and the recovery of cobalt from flotation of pyrite should be carried out before flotation of ilmenite. If the ore contains carbonate minerals, it must be pre-floated. There are two smelting methods for the extraction of vanadium in ferrovanadium concentrate: fire method and wet method.Web
