The principal gold minerals that affect the processing of gold ores are native gold, electrum, Au-Ag tellurides, aurostibite, maldonite, and auricupride. In addition, submicroscopic (solid solution) gold, principally in arsenopyrite and pyrite, is also important. The main causes of refractory gold ores are submicroscopic gold, the Au-Ag tellurides, and very fine-grained gold (<10 µm) locked ...

Sulphide, oxide, and mixed ore are fed to separate mineral processing circuits tailored for recovery of the dominant copper minerals in each. After comminution to a target grind size of 80% passing 150 μm, each ore type is subjected to flotation to recover the copper sulphide minerals (chalcopyrite, bornite, chalcocite, covellite).

The sorting of copper ore is mainly by flotation, and the joint process of reselection or smelting can also be used. Sorting of copper sulfide ore: different processes are used according to the nature of the ore： (1) To deal with copper ore embedded with very fine copper ore, choose stage grinding, stage flotation or multi-stage grinding, centralized flotation process.

Today, flotation is commonly used in the processing of primary copper–gold ores to produce a copper concentrate containing gold as a co-product, where the gold is recovered as a byproduct of copper smelting and refining (La Brooy, 1992). The gold is usually discrete and either free, associated with copper sulfides or associated with iron ...
