Pyrite as a sulfidation agent in chrysocolla sulfidation roasting for copper recovery: Thermodynamics, phase transformation, and sulfur migration

[Display omitted] •The recovery of chrysocolla through sulfidation roasting and flotation reached 87.31%.•The sulfidation reaction proceeded from the particle surface to the inside.•The sulfidation product on the surface of chrysocolla was chalcocite (Cu2S). Chrysocolla is an important refractory co...
