Battery-grade manganese sulfate is mainly used for the preparation of precursors of lithium battery positive electrode ternary materials (lithium nickel cobalt manganate); this dataset includes the main raw and auxiliary materials, energy use, atmospheric emissions, and water emissions in the production process, but infrastructure such as the manufacture of production equipment and plant construction is not within the boundary of this dataset; The data inventory is formed by merging data from multiple sources and has been partially corrected, supplemented, and perfected by referring to industry statistics, standards, and the pollutant discharge coefficient manual, etc.; the preparation of battery-grade manganese sulfate first involves leaching with manganese dioxide, pyrite, and concentrated sulfuric acid to produce crude manganese sulfate, followed by impurity removal and purification. The production process includes procedures such as feeding, ball milling and pulp preparation, acid leaching, pressure filtration, impurity removal, evaporation and crystallization, centrifugal separation, drying, etc.
