Properties of silicon manganese slag as an aggregate

2020-3-4  SiMn slag, a nonferrous metal, is generated in the smelting of SiMn, and has a high Si-based oxide content and low Fe-based oxide content. Frias et al. reported that the fine powder of SiMn slag is appropriate for the use as an aggregate in concrete because it increases volumetric stability when employed as a cement admixture [ 15, 16, 17 ].

Recovery of manganese from silicomanganese slag by

A hydrometallurgical process is proposed in this paper to recover manganese from silicomanganese slag. The paper reports the digestion–leaching experiments and precipitation and electrowinning assays to recover Mn from this residue. Silicomanganese slag was first treated with sulfuric acid in a furnace at 200 °C. It was then leached with water, CaO and KOH, and finally filtered to dissolve the manganese.
