Apr 03, 2014 · Beneficiation of Iron Ores. Iron ore is a mineral which is used after extraction and processing for the production of iron and steel. The main ores of iron usually contain Fe2O3 (70 % iron, hematite) or Fe3O4 (72 % iron. magnetite). Ores are normally associated with unwanted gangue material. Grade of iron ore is usually determined by the total ...

I.Ž. Tonžetić, in Iron Ore, 2015 Liberation, locking, and association. Historically, mineral liberation has been used as a proxy for the "processability" of a particular mineral, since the many properties of minerals that could allow for concentration and processing could not be directly measured from autoSEM instrumentation. Thus, the poor liberation of a mineral of interest in ...

The principal separation in iron ore beneficiation, therefore, is between the iron minerals, hematite and/or magnetite, and silica, principally in the form of quartz. The use of flotation, either alone or in combination with magnetic separation, has been well established as an efficient method for rejecting silica from these iron ores.
