Recyling manganese-rich electrolytic residues: a review

As a vital strategic mineral resource, the manganese ore is widely used in steel, non-ferrous metallurgy, chemical, electronics, batteries, agriculture, medicine, and other fields (Fig. 1).Based on the latest USGS 2022 data (Fig. 2a and Table 2), manganese ore reserves (by metal content) are mainly located in South Africa (about 640 million Reduction roasting of manganese ores is a known process; however, it is not yet commercialized mainly due to various techno-economic issues.

A Review of Low Grade Manganese Ore Upgradation Processes

Low-grade ferruginous manganese ores with Mn < 34% and Mn/Fe < 2.5 needs to be upgraded to enrich their manganese content before using them in the manufacturing of ferroalloys [1]. V Singh et alThe development of a hydrometallurgical process to recover manganese and silver from manganese–silver ores is reported. Insoluble manganese(IV) was reduced to soluble manganese(II) in an aqueous medium with calcium sulfide (CaS) as the reductant, and the resultant residue was then leached by a sulfuric acid solution.
