Efficiently separating malachite from talc using new

1. Introduction. Copper is widely used in many industries, including transportation, electronics, medicine, telecommunications and energy (Sun et al., 2018, Bai et al., 2019, Li et al., 2018).As copper consumption and demand increase, available copper sulfide resources are decreasing (Chen et al., 2014).The concentration of copper oxide ores has become increasingly critical.

Processing of Complex Materials in the Copper Industry

2020-7-6  A much more difficult mineral processing challenge is the selective flotation of arsenic-bearing copper minerals (e.g., enargite, Cu 3 AsS 4, and tennantite, (Cu, Fe) 12 As 4 S 13). These minerals have flotation characteristics very similar to non-arsenic-bearing copper minerals (chalcopyrite, chalcocite and bornite).
