Cyanide Leaching Process
2015-07-17 XinHai Views (2125)Cyanide Leaching process is the main method of extracting gold from the ore and the concentrate in modern time. It includes some basic steps, such as cyanide leaching, leaching pulp washing filter, pulp cyanide solution or cyanide gold extraction and smelting of finished products. Generally, two processes of gold extraction are used in cyanide gold extraction plant of Chinas gold mine. One is based on continuous countercurrent washing in thickener, and the gold is recovered by precipitation with zinc replacement, which is the so-called conventional cyanidation gold extraction process (CCD method and CCF law), the other without filtering and washing, it just use activated carbon to adsorb recovery of gold from cyanide pulp without filtering carbon pulp process (CIP and CIL law method).
According to different materials, conventional cyanidation of gold extraction process is used in two ways, the one is taken into handle the flotation gold concentrate or mercury amalgamation, and tailings re-election in cyanidation plant. And this kind of technology mostly applies to large state-owned mines, such as Hebei gold valley,WULONG in Liaoning, Henan Yangzhaiyu,Zhaoyuan, Xincheng, Jiaojia and Sanshan Island gold mine in Shandong province. The other is used to handle oxidized ore processing with full mud stirring cyanidation in the gold extraction plant, such as Jilin trench, Heilongjiang Tuanjie trench, Anhui New Bridge gold and silver ore mines and so on.
In the early 1930s,China started to use gold extraction cyanidation. Taiwan JInguashi gold mine adopted the method of cyanide - zinc replacement process to extract gold with the production of 150,000 annually during 1936 to 1938.
After entering the 1960s, in order to adapt to the development of the national economy, the percolation cyanidation gold extraction process was replaced by intermittent mechanical agitation cyanidation gold extraction process and continuous agitation cyanidation in some mines to increase the development of gold production in gold mine
In the terms of the nature of mines and the customer needs, Xinhai provided CIP and CIL to solve problems one after another. The idea of Cyanidation process won various of honors and praise for Xinhai itself.
