Method Of Magnetic Separation Of Iron Ore

China has proved that major iron ore deposits can be divided into 9 major categories.

     Anshan-type iron ore is the most important iron ore deposits, which total reserves are about 50%. Metallic mineral in ores is mainly magnetite, followed by hematite, siderite; gangue minerals are: quartz, chlorite, amphibole, mica, feldspar and calcite and so on.

     Jingtieshan-type iron ore are mainly distributed in northwest China's Gansu, the main ore of iron ore is a mirror metallic minerals, such as siderite, symbiotic valuable for barite mineral. The main gangue mineral is jasper, iron dolomiteetc.

     Panzhihua Iron is a companion-type vanadium, titanium, cobalt and other elements of the magnetite, the ore reserves of China's total iron ore reserves in the second. The main metal mineral ores are containing vanadium-titanium magnetite, ilmenite, pyrrhotite sulphides.

     According to the different iron minerals, the iron ores with the value industry are: magnetite rock, red iron ore, brown iron ore, iron ore and mixed Ling iron ore (magnetite, hematite, a mixed ore containing titanium magnetite rock, Cu-bearing magnetite stone) and so on.

Magnetic of magnetite stone

     Magnetite is a high school hot liquid rock contact metasomatic ore deposits, the most effective beneficiation method of the ore is magnetic separation, and a typical separation process as shown below. The period of more than or dry magnetic separation bis broken or minor sub-selected products of the sorting process is a pre-sorting operation.
    Dry magnetic is products mainly separated from tailings coarse-grained and deep-election for further. Products selected for further deep bis or three paragraphs by fine grinding and then bis or three wet magnetic separation, a final concentrate product is gained.
