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. ra...

This paper proposes a method to find gold deposits in the Eastern Desert of Egypt. Different methods including various classification methods, principle component transform (PCT), band ratios, and a constrained energy minimization technique are evaluated for their performance for hydrothermal alteration zone mapping. First, these techniques are carried out to highlight known gold deposits over ...
