In the process of gold beneficiation, flotation and cyanidation are mostly used to extract gold, and these processes will have a certain impact on the environment. After years of research and development, our company has successfully completed a new gold extraction process. The process does not use any chemicals and no pollution during the gold extraction process. It can be further removed from cyanide tailings or flotation by using electricity and part of the circulating water. Gold can also be recovered from the tailings by adopting the whole-process environmentally friendly gold extraction process.
