Gold recovery from mine tailings

Common gold mine tailings treatment methods: 1. Gold tailings reselection. The gold content in gold mine tailings is generally 0.2-0.6g/t. In addition to gold and silver recovery, the gold tailings re-selection process can also comprehensively recover other valuable elements according to the nature of the tailings
