The magnetic separator is one of commonly used preparation equipments in magnetic separation factory. It has dry and wet two types. According to types of magnets, it can be divided into permanent magnet type and electromagnet type. It is also can be divided into strong magnet type, middle magnet type and weak magnet type according to the magnetic field strength. Different magnetic separators have different characteristics and performance.
The common things have magnetite iron ore (belong to strong magnetic minerals), hematite (belong to weak magnetic minerals), limonite, lens iron ore, siderite (they are weak magnetic minerals), etc.
They are the raw materials of iron and steel industry, China’s iron ore grade is low, most of the impurities high, so more than 80 percent of the need for magnetic separation. Manganese, such as hard manganese, pyrolusite, rhodochrosite are weakly magnetic, commonly used in magnetic separation recovery.
Ilmenite, wolframite, monazite (phosphorus cerium lanthanum mine), niobium-tantalum minerals are weakly magnetic minerals. Also commonly used in the recovery of magnetic separation.
If the above examples are magnetic minerals as a purpose of mineral recovery (the magnetic minerals as a concentrate) is regarded non-metallic mineral beneficiation of iron, titanium and other mineral impurities harmful ingredients, generally magnetic method removed. For example, the beneficiation of kaolin, kyanite, quartz, feldspar, tourmaline, etc. are generally used magnetic separation to remove iron, titanium minerals.
Heavy media beneficiation ferrosilicon or magnetite to do to increase the quality, magnetic separation is a simple and effective method of recycling to increase the quality of this application, common in the coal preparation plant. The broken ore crushing crusher broken cavity into the Iron Crusher will be damaged, commonly used magnetic separation to remove the material in the iron. Comprehensive utilization of the useful ingredients in the processing of waste, wastewater, waste gas, such as “three wastes” to protect the environment, application of magnetic separation is also available.
Example, recycling steel slag in steel mills, power plants deal with fly ash, steel mill wastewater treatment, there is the method of magnetic separation. The magnetic fluid separation method is a new magnetic separation process, the use of a magnetic liquid in a magnetic field “may increase the role of objects immersed in the great magnetic force can separate objects of different density. The United States, Japan and other countries using magnetic fluid separation method to deal with auto junk, and our country are mainly used in the beneficiation of diamonds
