Reprocessing gold mine tailings

Nowadays, with the gradual exhaustion of mine resources, and the development of mineral processing technology, the issue of tailings reprocessing technology becomes more and more outstanding. People realized that useless tailings contained huge reused value, such as non-ferrous metals, ferrous metals and non-metallic minerals, etc
