  • Manganese processing Britannica

    To obtain a product of low carbon and silicon content, manganese ore, lime flux, and coal are fused in a furnace, forming a melt rich in MnO. This is then contacted with silicomanganese or low-carbon silicomanganese. The silicon in these alloys reduces the MnO to manganese metal and is itself oxidized into the slag. The carbon content of the particular silicomanganese reducing agent carries over to the final ferromanganese product—about 1 percent when silicomanganese

    A more progressive extraction process involves directly reducing manganese ore in a heap leach. This is done by percolating natural gas through the bottom of the heap; the natural gas provides the heat (needs to be at least 850 °C) and the reducing agent (carbon monoxide). This reduces all of the manganese ore to manganese oxide (MnO), which is a leachable form. The ore then travels through

  • Selective-Reductive Leaching of Manganese from Low

    Selective-reductive leaching of manganese from low-grade manganese ore using tannic acid as a reductant in acidic media was demonstrated by XRD, SEM-EDX characterization, and batch leaching studies at room temperature. The pH change in the liquid phase before and after leaching revealed that selectivity of manganese over iron was due to the hydrolysis of iron.
