A distinction is made between monomineralic ores, which consist of a single ore mineral, and polymineralic ores, which contain several valuable minerals and other, associated minerals with no industrial value. As a rule, ore minerals occur together with associated vein minerals. The ratio between ore and vein minerals varies greatly, depending on the metal and the given deposit. For example

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 Fe content in the ore. Run of mines ores after dry

Ores are usually found concentrated in deposits with a definite gradation of metal concentration from the ore to the surrounding rock. The ore often occurs in veins, which are orefilled fissures in the rock. The veins vary in thickness from only fractions of an inch to several hundred feet. Minerals with no commercial value, called gangue minerals, are usually found mixed with the ore in the
