Abstract

A concentrate having an iron content of at least 66% by weight, and a silica content of less than 2% by weight is produced from low grade specular hematite ore by grinding the ore to minus 10-28 mesh, subjecting the ground ore to a wet concentration, drying the resultant concentrate and subjecting it to electrostatic separation. Wet autogenous grinding is preferred and the wet concentration may be effected using Humphrey spirals or by froth flotation. The finer and coarser fractions from the grinding step may be processed separately and a magnetic separation step may be inserted between the grinding and wet concentration steps.
