Description
This dataset represents a product that is manganese oxide ore, whose main mineral components are psilomelane, pyrolusite and manganite, with an overall average grade of 17.9%. The mining method adopts a composite mode combining open-pit mining and underground mining, and the core indicators of the two mining methods differ: open-pit mining has an ore recovery rate of 95% and a dilution rate of 10%, corresponding to a raw manganese-ore grade of 17.9%; underground mining has an ore recovery rate of 85% and a dilution rate of 25%, corresponding to a raw manganese-ore grade of 14.87%. This manganese oxide ore is a naturally primary-mined ore and is the source core raw material of the manganese metallurgy industrial chain; the upstream is the manganese-oxide-ore primary ore-body deposit, and the downstream, through beneficiation and enrichment processes, can produce manganese concentrate, which is further used for smelting manganese-series alloys, producing electrolytic manganese, manufacturing chemical products such as manganates, and producing desulfurization and deoxidation additives for steel smelting. It is widely applied in metallurgy, chemical, electronics and other industrial fields, and is an important basic mineral raw material required for national economic development. The dataset includes the main raw and auxiliary materials, energy and wastes in the production process; infrastructure such as the manufacture of production equipment and plant construction is not included within the boundary of the dataset; the data inventory is formed by merging data from multiple sources.
Activity Description
The entire production process includes the mining process of manganese oxide ore, and the mining method adopts a combination of open-pit and underground mining.
Process Description
Manganese oxide ore is an ore mainly composed of hard manganese ore, pyrolusite and hydromanganese ore, with an average grade of 17.9%. Due to the combination of open-pit and underground mining, the ore recovery rate of open-pit mining is 95%, the ore dilution rate is 10%, and the original manganese ore grade is 17.9%; the ore recovery rate of underground mining is 85%, the ore depletion rate is 25%, and the original manganese ore grade is 14.87%.
