Introduction. According to the magnetic difference of various ores or materials, the crude ore or materials realize the final mineral separation under the magnetic force and other mechanical forces.Based on 20 years of mineral processing experience, Xinhai continuously develop and innovate magnetic separation process on the basis of the traditional magnetic separation technology, and has

Hematite ore dressing can be carried out by the methods of ore washing, gravity dressing, flotation, magnetic separation and roasting magnetic separation, or by flotation and electric separation as concentration operations.For coarse or massive ores mixed with depleted materials, heavy suspension is often used for ore dressing.

Separation Processes For Hematite. Separation processes for hematite The role of coagulants flocculants in solid liquid separation As discussed earlier filter aids can alter the material phase of the solids In some situations to aid in the filtration process it is necessary to change the effective particle size of the solids with coagulation and flocculation processes hematite separation by

For single hematite: 1. Roasting magnetic separation. Roasting magnetic separation is one of valid methods to separate fine from ultrafine particles (below 0.02mm). When the components are complicated and other beneficiation methods fail to meet related indicators, it is strongly recommended. 2. Gravity separation, floatation, strong magnetic

Hematite Separation Process. A hematite in Jiangxi with extremely fine particles distribution was colloidal hematite, which is very difficult to separate.

The core factor of magnetic separation process——Magnetic Susceptibility. Aiming at the characteristics of magnetic strength, Xinhai introduced different magnetic separation methods to process minerals with different magnetic strength. Weak magnetic field magnetic separation process is mainly used to recover strong magnetic minerals.

Magnetic methods are more popular in mineral exploration than gravity, not least because magnetic data can be quickly recorded from the air and in conjunction with other geophysical surveys. Land gravity surveys, by contrast, may require greater field efforts (Figs. 1, 5 and 6), more time, and more commitment of scarce capital.

According to the nature of the ore which containing hematite and magnetite,under the conditions,for example,ore grade is 24.07%,the first fineness of grinding -200 mesh is 50%，the second fineness of grinding -200 mesh is more than 95%, it is concluded that concentrating circuit consisting of first grind-Feebleness magnetic separation -high intensity magnetic separation，second grind-second

So when the strong magnetic separation process is adopted, the weak magnetic separation operation is usually added before the strong magnetic separation operation to remove or separate the strong magnetic minerals in the ore. In addition, hematite magnetic separation process can also adopt the strong magnetic-flotation process.
