Nov 01, 2019 Sulphide ores are the major source of valuable metals such as copper, lead, zinc, and nickel, as well as gold, silver, and platinum group metals (PGMs), and flotation is the dominant industrial process to recover these metals via the production of a sulphide concentrate.(SAG) mill together with the ore feed and process water.
Nov 26, 2019 Both the autogenous grinding mill and the ball mill feed parts are welded with groove and embedded inner wear-resistant lining plate.As the sag mill does not contain grinding medium, the abrasion and impact on the equipment are relatively small.
