Cyanidation carbon adsorption process is the most widely used in gold cyanide extraction process . The principle in brief is the carbon could adsorb liquid gold from cyanide solution . In 1970s, with the research and establishment of adsorption of carbon loaded with gold and the recovery of carbon discharge gold, make recycle the carbon and reduce the cost, and easy to process the gold ore with low grade .

Environment Tailings. Tailings are the product of processing ore to recover the contained metals. After extraction from the mine, the ore is crushed and subsequently ground to a particle size that allows for the liberation of the metals from the host rock. Most mineral deposits are composed of many different minerals, some of which contain metals.
