what is magnetic separation in chemistry ?
The ilmenite beneficiation process depends on factors such as deposit type, ore properties and mineral composition. In view of the relatively close nature of the original ore of titanium, the target mineral is relatively simple, so the beneficiation method and the beneficiation process are common. The primary ilmenites developed in the industry are composite deposits containing iron and titanium. The beneficiation process is divided into two parts: iron selection and titanium selection. The magnetic field of ilmenite magnetic separator has a peak magnetic field of 16,000 GS, which can effectively recover strontium, manganese ore, ilmenite, chromite ore, ore and tungsten in minerals. It can also be used for non-metal feldspar, quartz, calcite and kaolin. The equipment is exported to Africa, Mexico, Iran, Bastan and Malaysia. The equipment adopts advanced technology, and all the magnetic blocks used in the NdFeB rare earth materials are processed by different ratios, different firing temperatures and different processes. The magnetic field is stable without demagnetization, and there is a high temperature magnetic separation equipment for high temperature environment beneficiation operation, 5 The demagnetization rate was less than 10% during the year. The raw material of the titanium plant is iron ore tailings. The titanium selection method includes reselection, magnetic separation, electric selection and flotation. There are several industrial processes for selecting titanium:
(1) Re-election. The electro-election process uses the re-election method to discard low-density gangue or waste rock minerals, and the obtained coarse concentrate is electrified to obtain ilmenite concentrate. For sulfur-bearing ores, it is necessary to remove the sulfide minerals by flotation prior to electrification.
(2) Re-election. Magnetic separation. Flotation process. The selected materials are first classified, the coarse particles are selected by re-election and magnetic separation, and the fine particles are obtained by flotation.
(3) coarse grain re-election. Electro-election, fine-grain magnetic separation. Flotation process. The process is characterized in that the selected materials are divided into two parts, coarse and fine, the coarse particles are treated by re-election and electro-selection, and the fine particles are coarsely selected by magnetic separation, and then the fine-grained titanium is obtained by flotation. Concentrate.
(4) Single flotation or magnetic separation. Flotation process. For the ilmenite ore with fine grain size, after the iron is selected, the titanium concentrate is directly obtained by flotation or the wet magnetic separator is used as a roughing device, and then the magnetic separation concentrate is used to recover titanium by flotation. Single flotation method or magnetic separation. The flotation process is relatively simple and easy to operate and manage, but the use of flotation reagents will increase the cost of dressing.
