The chemical composition of hematite is Fe2O3, and the crystal belongs to the hexagonal oxide mineral. It is homogeneous with maghemite of equiaxed crystal system. Its appearance is steel gray, metallic luster, scale-like called mica hematite. Hematite is a secondary mineral widely distributed among various rocks. It appears in finely dispersed granules in many igneous rocks. In special cases, it forms huge blocks in regional metamorphic rocks. In red sandstone, hematite is a cement of quartz particles and colors the rocks. To be economically exploitable, it must contain tens of millions of tons of hematite, which is caused by a large scale of sedimentation. There are many such iron ore in the Precambrian strata, which usually contain silicon. Impurities.
The hematite production line is mainly for the processing of hematite production process. The basic beneficiation process is: stage grinding or continuous grinding-weak magnetic separation-high gradient strong magnetic separation-anion reverse flotation process. According to the different ore properties of hematite grade and gangue mineral composition, coarse subdivision and other processes can be carried out, and coarse particles can be re-elected. The hematite mineral is processed and used in various industries, such as chemical industry, mineral processing and other industries.
1. Broken and sieved. The mined hematite is uniformly and continuously fed from the feeder to the jaw crusher, and preliminary crushing is carried out in the jaw crusher; the hematite which is initially crushed enters the vibrating screen by the jaw crusher and is sieved. Material, producing a sieve and a sieve;
Grinding and grading. The sieved good hematite mineral material is sent to the ball mill from the vibrating screen via the hoist and the feeder to be pulverized and ground again; the ground hematite fine material enters the classifier and precipitates in the liquid due to the specific gravity of the material. Different principles are used to wash and classify materials;
Magnetic separation, drying. After the materials washed and classified in the classifier enter the magnetic separator, the magnetic materials are separated due to the different magnetization coefficients of the mixture; the separated materials contain a large amount of water, and then are dried by the dryer. Dry work to get a dry finished product.
This production line is of compact and reasonable structure, lower investment, convenient maintenance and wide application range, which is used in a variety of stone crushing and ore crushing. It is the best choice for projects in primary and medium scale.
Hematite Separation Process
Hematite separation process is suitable for complex structure hematite such as hematite and impurities with uneven distribution of particle size, ore with large content of fine particle, ore with small amount of magnetite and the gangue minerals containing quartz or kaolin.
