all-slime cyanidation technology is a technology process which put activated carbon into pulp and leaching with absorbing gold at the same time. It includes the stages such as leaching pulp preparation, leaching and adsorbing, gold removal carbon recycling, pulp agitation, and gold loaded carbon desorption. It suits for large gold mines with
