The process of separating manganese from iron has a wide range of applications. Elements with lower or equal decomposition temperatures to manganese, or those that form soluble sulfates, will be leached out with manganese sulfate. A more advanced method for extracting manganese involves directly reducing manganese ore in a heap leach.
