Abstract

A method for production of iron ore concentrates comprising the steps of: crushing low grade ore, slimes and other deposits to produce iron ore particle of the size less than 1.5 mm; subjecting the said particles to the step of selective separation to isolate iron ore mineral from gangue minerals; and obtaining enriched ore with high iron content from (60% to 67%) using low intensity magnetic separator (LIMS) and high intensity magnetic separator (HIMS).
