Read more +In bacterial leaching, certain strains of bacteria are used to liberate gold or base metals from their mineralogical host.They metabolize energy from the oxidation of ferrous iron andor sulfur compounds and free gold or metals in the process.This can take place in a heap, vat or column of crushed or ground ore.
Read more +The process is characterized for its economic cost against the agitated leaching process when the ore deposit has a low gold content.Typically the process can process ores whose gold content is 0.8-1.1 gt.The leaching solution is spread at the top of the pile and the pregnant solution will have to percolate through the pile.
Read more +Gold is processed by cyanide milling, a chemical procedure that separates 95 to 98 percent of the gold from raw mined ore.It is then refined to the gold standard purity, according to mineweb.Heap leaching is a less expensive method of gold extraction, but it is a longer process and it recovers less gold than the cyanide milling process.Get price.
