[0002] Tailings treatment is an important part of the mining and smelting industry. It mainly refers to the treatment of useful metals and other harmful substances that have not been extracted from metal ores to reduce environmental pollution and waste of resources. At present, non-tailings treatment or metal tailings treatment mainly adopts the following methods:
