The leaching of carbon-containing gold ore. In recent years, Chinas mining efforts have continued to increase, and mining equipment occupies an irreplaceable position in the mining of mining resources. Generally, coal ore is accompanied by gold minerals, and carbon is adsorbed and dissolved in the mine to carry out gold ore.
5.The existence of insoluble gold compounds . In some ores, gold exists in the form of tellurides such as tellurium gold ore, tellurium silver gold ore, tellurium antimony gold ore, tellurium copper gold ore, solid solution silver gold ore and other alloys. They play a very important role in cyanide solution. slow.
