Iron Ore Beneficiation Process

During the last ten years great strides have been made, on the Mesabi range, in the practice of beneficiating low grade iron ore material. By beneficiation is meant all methods of removing impurities, and raising the iron content to a point where it can be sold in open market, the principal impurities being silica and moisture. The general processes to which low grade iron ores are amenable

Characterisation and magnetic concentration of an iron ore

Jan 01, 2019· The Minas Gerais State (Quadrilátero Ferrífero) is the biggest iron ore producer (64.8%) in Brazil. Owing to the low grade of the iron ore (31–45 wt% Fe), beneficiation is mandatory in Quadrilátero Ferrífero. Beneficiation for the steel making industry consists of comminution and size classification followed by concentration.
