Mineral processing separates them from each other in different ways depending on the physical properties and physicochemical properties of the various minerals in the ore. For example, according to the different properties of mineral particle size, shape, color, gloss, specific gravity, friction coefficient, magnetic permeability, electrical conductivity, wettability of mineral surface, etc., different beneficiation methods are selected to achieve separation of useful minerals and gangue minerals. the goal of.
Commonly used mineral processing methods include: re-election method, magnetic separation method, flotation method, electric separation method and chemical beneficiation method.
Gravity beneficiation (re-election) is an ancient beneficiation process that separates minerals based on differences in mineral density (or particle size). Mineral particles of different density (or particle size) are subjected to hydrodynamic forces and various mechanical forces in the moving medium (water, air and heavy liquid), resulting in appropriate loose delamination and conditions, resulting in different densities (or particle sizes). The ore particles are separated from each other. Reselection method is widely used for sorting tungsten, tin, gold, and other metals (Fe, Mn) ore; non-ferrous metals, rare metals and non-metallic ore sorting often using gravity separation.
The magnetic separation method is a method of sorting according to the difference in mineral magnetic properties. It is mainly used to select ferrous metal (iron, manganese, chromium ) ore; it is also used for the selection of non-ferrous metals and rare metal ores.
Flotation is a method of sorting minerals based on differences in the physicochemical properties of mineral surfaces. Flotation is extremely common and can be used to treat most ore. For example, non-ferrous metals such as copper , lead , zinc and molybdenum are mainly treated by this method; ferrous metals, rare metals and non-metallic ores are also commonly selected by flotation methods. Most of the vein gold mines use flotation to recover gold.
Electroporation is a method of sorting ore based on the difference in mineral conductivity. When the ore passes through the high-voltage electric field in the electric separator, the electrostatic force acting on the mineral is different due to the difference in the conductivity of the mineral, thereby separating the mineral. Electroporation is mainly used for the selection of rare metals, non-ferrous metals and non-metallic ores.
The chemical beneficiation process is a process of enriching and recovering useful components in ore by using chemical, chemical, and metallurgical principles and processes. This method is mainly used to deal with poor ore, difficult ore and multi-metal complex mines that cannot be used economically and effectively by physical and mechanical methods. In the process of recycling gold, chemical dressing occupies a very important position.
In addition to the above-mentioned beneficiation methods, there are also methods such as hand selection, friction selection, and photoelectric selection. It should be noted that in practice, for a particular ore, not only a single beneficiation method, but a combination of two or more methods is employed to achieve the full and effective use of various useful metals.
The ore from the stope is subjected to various operations in the beneficiation process, and finally the concentrate that meets the next treatment is obtained. The operations of the mineral processing process mainly include:
1. Preparation: including crushing and sieving, grinding and grading of ore.
2. Sorting work: mainly refers to various sorting processes, such as re-election, magnetic separation, flotation, cyanidation, etc.
3. Dewatering operation: including concentration, filtration, drying, etc.
