Which equipment is needed in mining beneficiation

The Beneficiation includes three categories of re-election, flotation and magnetic separation. We should construct a reasonable choice according to the beneficiation of ore grade, and configure beneficiation equipment according to beneficiation type. The common beneficiation equipment includes: Impact crushing machine , Magnetic separator (wet and dry magnetic separator, high gradient magnetic separator), flotation machines (usually floating sorting machine and inflatable flotation machine) concentrated machine, mixing drum, Vibrating feeder , tailings recycling machines, spiral classifier, spiral chute and other equipment.
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 flotation concentrator have different characteristics and performance.
In magnetic separation practice, the mineral is divided into strong magnetic minerals, weak magnetic minerals and the nonmagnetic minerals according to the size of specific susceptibility.
① Weak magnetic minerals: This kind of mineral belongs to the ferrous magnetic material, such as magnetite, magnetic pyrite, magnetic hematite and zinc, iron spinel, etc. This kind of mineral can be recycled by magnetic separation machine with weak magnetic field intensity.
② strong magnetic minerals: they can be recycled by strong magnetic separation machine with magnetic field intensity H = 1 ~ 2 T. there are many mineral of this kind, such as iron mn, hematite, mirror, limonite and iron ore, manganese ore, using, soft hard titanium iron ore, chromite, black tungsten mine, etc. Part of the rock minerals such as black made mica, Angle flash stone, chlorite, hauling, olivine, garnet, electrical stone, pyroxene, etc. This kind of mineral mostly belongs to the magnetic material, also have the ferromagnetic materials.
③nonmagnetic minerals: In the current technology conditions, it still can’t be recycled by the magnetic separation method.
