iron ore magnetic concentration process

Magnetic separationis an old technique for the concentration of iron ores and for the removal of tramp iron. Since 1849, a number of patents on magnetic separation have been issued in USA, and texts of some of the patents before 1910 describe a variety of magnetic separators for mineral processing.

    Extraction of Iron & Concentration of Ore An Overview

    Concentration of Ore The extraction of iron begins with concentration throughcalcinationwhich is a process in alimited supply of oxygen applied to ores to bring thermal decomposition. An ore of a metal is an impure source. It consists of many impurities other than metal such as sand, clay, etc.

    Magnetite, ideal formula Fe 3 O 4, is an intriguing mineral not only because it ismagnetic.The formula could be written as Fe 2 + Fe 3 + 2 O 4, which more precisely designates one of its peculiarities.It contains both ferrous (Fe 2 +) and ferric (Fe 3 +) ions, implying synthesis, growth, and stability within an environment where oxidized and reduced states ofironare present and maintained.

    Ironprocessing -Ironprocessing - Ores:Ironores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributediron-bearing minerals are oxides, andironores consist mainly of hematite (Fe2O3), which is ...
