The main difficulty in sorting copper-bearing pyrite is that this type of ore has high sulfur content and is very easy to oxidize. During the oxidation process, the primary chalcopyrite in the ore may form three types of substances: secondary copper sulfide (chalcocite and digenite), water-soluble copper (chalcanthite and pisanite), and malachite and azurite.

Pyrite flotation separation and encapsulation in tailings dams is proposed as a viable way to chemically stabilize tailings. Characterization of potential acid mine generation in tailings led to an innovative process in which acid-generating pyrite is separated by flotation from the coarse tailings and incorporated into the slime zone. This creates pyrite-free neutral tailings …

Globally, the mining industry processes millions of tons of ore daily, generating a large amount of waste. More than 95 % of these are deposited as dumps or tailings (Falagán et al., 2017), generating between 5 and 7 billion tons of mine tailings (MTs) annually worldwide (Edraki et al., 2014).In the case of Chile, the mining industry is strongly developed.
