Method of mineral processing equipment for beneficiation and main points of ore dressing method

January 22, 2020

The beneficiation equipment is an element that constitutes the beneficiation process, and the different beneficiation processes are not the same. The ore dressing methods include re-election, magnetic separation, electric selection, flotation, chemical selection, photoelectric selection, friction selection and hand selection. Every method of beneficiation has its own weight. Let me introduce the method of mineral processing.
1. Re-election, the full name of gravity beneficiation, is a mineral processing method for separating minerals according to different mineral densities. In addition to various re-election equipment , there must be a medium (air, water or heavy liquid) for re-election. During the re-election process, the ore particles are subjected to gravity (mainly centrifugal force in the centrifugal force field), the mechanical force exerted by the equipment and the force of the medium. The ingenious combination of these forces makes the mineral particles with different densities produce different speeds of movement and The trajectories of motion can eventually separate them from each other.
2. Magnetic separation is a mineral processing method that separates minerals by utilizing differences in mineral magnetic properties. Magnetic separation is performed in the magnetic field of the magnetic separation device . Different magnetic ore particles generate different motion trajectories due to different magnetic forces of different sizes, so they can be separated.
3. Electro-election is the separation of minerals by the difference in electrical properties of minerals. The electric selection is carried out in the electric field of the electric separator. Different electric ore particles are subjected to different electric field forces due to different charging forces, thereby generating different motion trajectories and finally achieving separation.
4, flotation full name floating mineral processing, is the use of the difference in the physical and chemical properties of mineral particles surface, from the pulp in the process of sorting minerals by means of buoyancy of bubbles. In the pulp, various flotation agents are added, and the selective adsorption of the ore particles to the chemicals is added to the pulp to add various flotation agents, and the selective adsorption of the particles to the agents causes a difference in floatability, and when the slurry enters the float When the machine is selected, a large amount of diffuse bubbles are generated by stirring and aeration. The ore particles suspended in the slurry collide with the bubbles, and the floatable particles are attached to the bubbles, floating up to the surface of the ore to form a foam product, and the non-floating particles are Stay in the slurry, which achieves flotation separation. Flotation must be carried out in a slurry of solid-liquid, one-gas, three-phase, and the addition of appropriate flotation reagents is the key to flotation.
5. Chemical separation, chemical mineralization, is the use of chemical treatment (such as roasting, leaching, extraction, precipitation, etc.) or chemical treatment combined with physical beneficiation, so that the useful components are enriched or purified. And ultimately produce chemical concentrates or products.
6. The photoelectric beneficiation method is based on the difference in photoelectric properties (color, reflectivity, excited light and transparency, etc.) between minerals, using the photoelectric effect, using the mineral separation method of mechanical sorting minerals.
7. The friction dressing method is sorted according to the difference of the friction coefficient and elasticity of the mineral. The selection process is generally carried out on a slope. Different friction coefficients and elastic minerals collide with the slope to produce different bounces. Different motion speeds along the slopes form different motion trajectories and eventually separate from each other.
8. The hand selection method is a method of manual sorting according to the difference in appearance of the ore (generally color and gloss) which can be observed by the naked eye.
