Gold extracted from gold ore process uses more is re-election and flotation, gravity separation occupies a very important position in placer gold production, flotation rock gold mine in wide use in the method of rock about 80% of the current gold mine using this method with gold. Before the 1970s, gold production in the early stages of development, except for a few of mine started using cyanidation gold extraction process, the mine on the property gold placer re-election, mainly from income of natural gold ore smelting, now with the science and technology development of gold processing technology and equipment have been greatly improved.

Gold Screening Process

A full set of gold processing equipment including mining equipment, crushing and grinding equipment, re-election and flotation devices. Crushing and grinding process is the most important gold processing equipment. First down its mining ore block uses jaw crusher for crushing coarse crushing, using standard cone crushing machine broken, and crushing with short head type cone crushers, grinding using a vertical milling machine . Liming has been committed to its crushing grinding metal ore and non-metallic mineral, which is commonly used in small selected gold plant they use a closed-circuit crushing two large selected gold plant using a closed-circuit crushing three-stage process.

To improve mineral production capacity, potential mining equipment for crushing process was modified so that the mill for grinding improved utilization factor, the main measures taken is the implementation of more crushing less grinding, reducing the size of ore into the mill, extended equipment life.
