Scope
Main technical content: This standard specifies the technical requirements, test methods, inspection rules, packaging, marking, transportation, storage, quality forecast forms, and order forms (or contracts) for crude manganese carbonate produced after impurities are removed from cobalt-nickel raw materials by smelting. This standard applies to crude manganese carbonate. This product can be used as a raw material for manufacturing soft ferrite magnets for telecommunications equipment, synthesizing manganese dioxide, preparing battery-grade manganese sulfate, and manufacturing other manganese salts.
