Abstract. Salt-type minerals flotation is discussed, based mainly on experiments on magnesite, dolomite and calcite. Among the parameters affecting flotation, the following are examined : crystal structure, solubility of minerals, surface charge, collectors, organic and inorganic modifiers, adsorption, contact angle and floatability.
The multi-element and XRD diffraction analysis of a magnesite in Xinjiang shows that the main component of the ore is MgO, which exists in the form of magnesium carbonate, and the gangue minerals are quartz, dolomite, calcite, etc, which are considered as fourth industrial grade products.

The first rule deals with the conservation of mass. The total flow of the material into the process plant equals the total flow out. The second rule relates to the quality or grade of the concentrate product. In practice, it is impossible to produce a concentrate consisting of only one mineral. The third rule is a corollary of the second.

1. Hand Separation method. In the 1950s and 1960s, manual beneficiation was one of the main beneficiation methods in the production of lithium concentrate and beryl concentrate at home and abroad. For example, in 1959, the hand-selected beryl concentrate in Xinjiang, Hunan and other provinces and regions in my country reached …
We investigated whether the vertical roller mill can be efficiently used in the beneficiation of low-grade magnesite and whether it can improve upon the separation indices achieved by the ball mill. We conducted experiments involving the reverse flotation and positive flotation of low-grade magnesite to determine the optimum process parameters, and …
The hard coal beneficiation process in mechanical preparation plants generates coarse, small or fines rejects and coal tailings slurries. The tailings are the finest grain size, with the majority below ~ 0.25 mm, whereby material sized below 0.035 mm makes up to 60% share in the slurry composition.
In the case of dry dense medium processes, air/magnesite or air/sand suspension is utilized rather than water/magnesite or water/sand slurries, which are commonly used in conventional dense medium cleaning processes. ... In 2020 207.2 Mt of coal were processed at coal beneficiation plants: ... The basic steps of beneficiation process …
