Lowgrade ore is a term applied to ironrich rocks with cutoff grades in the range of 25�30% Fe. It was the main supply of iron ore for many centuries of the World's early history of production of iron. Since the 1950s North America's main supply has been lowgrade ore. The dominant economic iron mineral in lowgrade ore is magnetite.

Jan 01, 2015 · The iron ore in this area contains a large volume of fines (20–30% below 150 μm), which can be transformed by high moisture content into a sticky mass that is almost impossible to screen. Vale initially considered wetprocess screening using water sprays to overcome the problem but ultimately rejected that approach as too costly.

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 ...
