Low Intensity Magnetic Separator

Many nonferrous and rare metal minerals are magnetic in different degree, while others do not. Following on from the Liming heavy industry to explain the application of magnetic technology in mineral processing. The single gravity separation and flotation method was not qualified concentrate, requires a combination of magnetic separation and other methods to obtain the qualified concentrate. For example, the re-election of the black tungsten tungsten coarse concentrate, containing tin and other useful components. Tin is a harmful impurities in tungsten smelting process. The use of wolframite and cassiterite has weak cashmere the characteristics of magnetic treated by magnetic separation, can remove the tin containing impurities, get qualified tungsten concentrate. The use of manganese and iron as medium in heavy medium separation, they have to move into the light, heavy product washing water in heavy medium separation process, the recovery and the reuse by magnetic separation method.Non metallic mineral processing of raw materials, and in many cases are accompanied by removal of iron, magnetic separation has become one of the most important operations. For example, kaolin iron is a kind of harmful impurities. Iron is high, the whiteness of kaolin, refractory and insulation are reduced, seriously affect the quality of the product, generally if the iron containing impurities 1~2%, can improve the whiteness of 2~4 units. The world of kaolin, and the application of high gradient magnetic separation device to remove iron impurities and obtained good results. Kyanite, quartz, feldspar, red tourmaline, nepheline syenite diorite since early in the dry magnetic separation method. For example, the Soviet Union, Canada, India and other countries USA nepheline diorite mineral processing, in order to remove the strong magnetic minerals, the use of weak magnetic separation machine, and with strong magnetic separator to remove weak magnetic minerals in non magnetic products (such as hematite). Into the concentrator ore often contains iron, it is easy to damage the crusher. In order to protect the machine from being damaged, liming heavy industry in the crusher to ore belt is suspended magnet to iron out in ores.

Magnetic separation is refers in the manganese ore dressing, a processing method that different mineral separation between the difference of magnetic minerals in inhomogeneous magnetic field. Don't choose the magnetic method is widely used in ferrous metal ores, non-ferrous and rare metal ore separation, medium recovery in heavy medium separation, remove from non metallic minerals iron impurities from iron, protection of crusher and other manganese ore dressing equipment, from steel slag in the production of scrap from the production and income and removal of pollutants in domestic sewage. Magnetic separation is mainly of processing Manganese ore dressing method. According to the magnetic separation flotation of manganese ore size, magnetic separation holds the important status in our country, the Soviet Union, Canada, Switzerland, America song and Norway and other countries. Manganese ore after separation, improve quality, reduce the content of harmful impurities in silicon and two, smelting process to bring many benefits. According to the practice of statistics in China, every 1% increase in manganese concentrate grade, the utilization coefficient of blast furnace can be increased by 2~3%, the coke consumption can be reduced by 1.5%, the limestone consumption can be reduced by 2%.
