Reduction roasting-acid leaching process was utilized to process high-iron-content manganese oxide ore using black charcoal as reductant. The results indicate that, compared with the traditional reductant of anthracite, higher manganese extraction efficiency is achieved at lower roasting temperature and shorter residence time.
found in New Zealand. Worldwide, these deposits are mainly silicate ores, with less common carbonate ores, and rare, oxides ores. 1.2. Manganese Alloy The production of manganese alloy from manganese ore is an energy intensive process and therefore, apart from manganese ore, power plays an important role in the production of ese alloy.
