Mineral processing - Wikipedia

Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue.

Iron ore - Wikipedia

This stockpile of iron ore pellets will be used in steel production. Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe

Different Types of Iron Ore - Mineral Processing Metallurgy

Impurities in Iron OresIron Ore FormationOrigin of Iron Ore-BodiesMagnetiteLimoniteSideriteThere are certain impurities that lower the value of iron ores or may even make them valueless. Sulphur in the ore goes partly into the iron and steel and makes them brittle. While it is possible by roasting the ore and by other means to remove the sulphur, the presence of any considerable amount is objectionable. Phosphorus in steel makes it brittle. For steel-making the limit for phosphorus is one hundredth of one per cent for ten per cent of iron in the ore; this is the so-called Bessemer

Iron Ore Mining Techniques, Metal Extraction, Types of

Iron ores are rocks and mineral deposits from which clanging iron can be reasonably extracted. Iron ore mining is classified into two categories- manual mining and mechanized mining methods. Haematite and magnetite are the most commonly found iron ore minerals. Deposits of iron ore such as haematite containing iron oxide are found in sedimentary rocks from which the oxygen is removed from the
