It is customary, therefore, to make a fourfold division into (1) manganese ores, (2) manganiferous iron ore, (3) manganiferous silver ore, and (4) manganiferous zinc residuum. Manganiferous iron ores found in the United States consist chiefly of limonite or hematite mixed with psilomelane, pyrolusite, or wad, the mixture being an intimate one.

and friable. The unaltered ore is of the hard variety. The soft ore has resulted from the leaching by percolating waters of the soluble lime carbonate contained in the hard ore. This alteration occurs at the outcrop of the ore beds and down the dip to varying distances, depend ing on the thickness and permeability of the cover.

Manganese ore originates as a carbonate, semi-carbonate, or oxide ore. 80-90% of mined supply ore is used in steel and speciality alloys sectors. The global manganese market is circa 20mt per annum of contained manganese. In 2020, the battery grade market represented 0.5% of the total contained manganese consumption.

The practice of manganese ferroalloy smelting has traditionally been based on utilising oxide ores which typically contain a high level of manganese. This preference for oxides has even been extended to the modification of natural carbonates into nodulized oxides. However smelting practices developed over the past 30 years have created a market for natural manganese carbonate ores, driven in ...

Electrolytic manganese is a refined manganese product created through the purification and electrolysis of a manganese-rich solution that is made by dissolving manganese carbonate ore or calcined manganese oxide ore. There are two primary forms of electrolytic manganese: Electrolytic Manganese Metal (EMM) and Electrolytic Manganese Dioxide (EMD).
