Production practice, the flotation process of renovating and many scientific research achievements, the effect is obvious. Floating stage grinding process, the heavy - float joint process, etc., is the main trend of development of flotation technology in China. Use heavy - floating joint process, such as xiangxi gold mine of stage grinding stage, don't get a good indicators, improve the...

Most traditional crucible method is used to mine in situ smelting smelting, due to the production process and the different nature of material, of gold from the gold content is different also, directly sell bank due to the high gold or silver not denominated in reason, some mines to improve the quality and economic benefits to the chemical method in smelting again or electrolytic process for...

In the late 1970 s, China portable gold wash plant began to low grade gold bearing oxidized gold ore heap leaching production technology research, in liaoning dandong wuhushan mine after the small-scale production experiment of silver lake, hole slope successively in henan spirit, yunnan sumie, hebei worship ceremony, chifeng in Inner Mongolia and other regions of the mines to...

China's gold heap leaching sodium cyanide price method is used to produce gold annual output reached more than two thousand (only gold heap leaching of gold production in henan province is 1.3 two thousand), but compared with developed countries, our country gold heap leaching smaller, generally 1 x 103 ~ 3 x 103 t/heap, wan t/heap is less, also there is a big gap on technology, in...

All slime cyanidation leaching gold technology is increasingly applied, successively in jilin, hebei, henan, shaanxi, Inner Mongolia and other places adopted factory of gold. At the same time, to solve the argillaceous oxidized chrome washing machine ore in dense filtration solid-liquid separation difficulties, in November 1979, changchun institute of portable gold ore sieve to unite...

Around 80% of the rock in China tin beneficiation plant portable trommel flotation method is used to choose gold, gold concentrate more sent to the output of nonferrous smelting processing. Due to the growing development of the cyanidation of gold, and the enterprise to improve economic efficiency, reducing loss of concentrate transport, so many take on-site processing (of course, due...
