Valuable metals substance flow analysis in high-pressure acid leaching
Substance flow analysis (SFA), an analytical tool, was applied to a high-pressure acid leaching (HPAL) process of laterites. The results show that although the HPAL process has become the mainstream process for the treatment of laterites, a large amount of solid waste discharge has caused great harm to the environment and restricted its large-scale …
