Calcite | mineral | Britannica

Calcite, the most common form of natural calcium carbonate (CaCO 3), a widely distributed mineral known for the beautiful development and great variety of its crystals. It is polymorphous (same chemical formula but different crystal structure) with the minerals aragonite and vaterite and with several forms that apparently exist only under rather extreme experimental conditions.

Reduction of Manganese Ores in CO-CO 2 Atmospheres

 · Manganese ferroalloys are produced in submerged arc furnaces, where the carbon and energy consumption of the process will be largely dependent on the solid-state reduction of manganese ore at relatively low temperatures. Higher manganese oxides (MnOx, x > 1) in the ore will reduce to MnO by CO(g) present in the furnace gas when exposed to elevated temperatures.
