Manganese extraction processes

Jan 19, 2021 The ferrous sulfate-sulfuric acid leach process for extracting manganese is a versatile and technically feasible process which can be adapted to fit a variety of circumstances. Figure 3 shows an example that could be used. The process flowsheet may be altered somewhat depending on the characteristics and composition of the ore to be leached
