Comprehensive Recovery of a High-sulfur Copper-gold Ore in Shandong

Abstract The raw gold grade of a mine in Shandong is 1.42 g/t, and it accompanied by copper sulfur minerals, the embedding closely related, so difficult to obtain ideal index using original flotation process. In order realize effective recovery gold, copper, sulfur, test study mixing-separation priority carried out. results show that mineral more suitable for beneficiation process flotation. rate 70.42%, 93.58%, 68.85%, 22.89% higher than produced mixed concentrate can be directly sold sulfur.
