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 Fe content in the ore. Run of mines ores after dry or wet sizing, if it

Many minerals contain iron, but the primary sources of iron ore minerals used to make iron and steel are hematite, magnetite, goethite, siderite, and pyrite. Hematite and goethite ores are most desirable because of their high iron content and ease of processing. Magnetite ore is increasingly being mined as more preferable deposits are becoming scarcer. Other less common iron-bearing minerals
