beneficiation of gold mine tailings dams

PRECIOUS METAL BENEFICIATION PROCESS The precious metal minerals are mainly gold and silver mines Xinhai Mining has more than 20 years of experience in beneficiation for gold and silver mines especially gold ore beneficiation technology gold gravity selection process and placer gold selection process Jul 21 2021 Due to the special role of gold the extraction of gold from the tailings of gold concentrators has received more attention Due to the backward technology of gold mining and beneficiation and smelting in the past the practice has proved that a considerable part of precious metal elements such as gold and silver are lost in the tailings Mining and beneficiation techniques are important underground mining a noted above creates much smaller volumes of waste per unit of metal than does surface mining and the higher the recovery rate during beneficiation the smaller the amount of tailings created
