The most commonly treated gold mines are placer gold mine and rock gold mine.
Generally, gold ore is low in content and complex in composition. The commonly used separation process of crushing and screening in the industry is mainly composed of three-stage and a closed-circuit process, that is, crushing the mineral to a proper size through coarse crushing, medium crushing, fine crushing, and screening.
The gold mining equipment in the crushing and screen stage jaw crusher,impact crusher, cone crusher,vibrating screen.
The grinding operation of rock gold mine usually adopts one section or two sections with lattice and overflow ball mills.
The second stage grinding operation forms a closed circuit with a spiral classifier or a hydro cyclone to ensure the grinding fineness.
In view of the shortcomings of traditional mills, such as fast wear and large energy consumption and other large-scale mining machine manufacturer of ball mill in a series of transformation, adopt new wear-resisting rubber lining board, sliding bearing with improving the mill operation efficiency, and also prolong the service life of the equipment, create economic benefits for enterprises.
The gold mining equipment in the grinding stage ball mill,rod mill, Raymond mill,ultrafine mill.
Placer gold mine and rock gold mine is the most common gold beneficiation types.
The gold concentrate content of placer gold ore is high and mostly exists in the form of sand particles. Therefore,the gravity process is mostly used in the beneficiation process. After pretreatment, desilting and washing the ore,and then using the method of gravity, which can be obtained the placer gold mine.

The mainstream gold beneficiation process flow is generally crushing 8211 grinding 8211 gravity separation 8211 flotation 8211 chemical 8211 smelting.
Gravity separation process and flotation are the most used gold mining methods around the world.
Gravity beneficiation is refers to separating gold ore according to mineral density and plays an important role in contemporary mineral processing methods. The main gravity separator equipment are chute, shaker table, mineral jig, hydrocyclones, etc.
Flotation process is widely used for lode gold processing. In most cases, the flotation method has a good effect in sulfide-containing gold ore with high floatability.
In addition, the flotation process is also used for polymetallic gold-bearing ores such as gold-copper, gold-lead, gold-copper-lead-zinc-sulfur ore.
What8217re the limitations of the flotation method For the ores with particle size greater than 0.2mm, and the quartz gold-bearing ore containing no sulfide, it is not suitable to use the flotation method.
There are amalgamation gold extraction process and cyanide process gold extraction.
The amalgamation process is an old gold extraction process, simple and economical, suitable for the recovery of coarse-grained monomer gold, but it has pollution to the environment and is was gradually replaced by gravity separation, flotation and cyanidation process.
The cyanidation gold extraction process includes cyanide leaching, cyanide pulp washing and filtration, extraction of gold from the cyanating solution or cyanide pulp, and smelting.
