Ecotoxicological consequences of manganese mining …
Crustaceans and molluscs are the most manganese-sensitive invertebrates. The Mn surplus produces a ca 2+ pump dysfunction, eventually affecting the neuromuscular transmission in marine invertebrates [34]. Through the process of photochemical and chemical reduction of this manganese oxide various free Mn is released into the water.

Recovery of Manganese Ore Tailings by High-Gradient …
With the depletion of high-grade manganese ores, Mn ore tailings are considered valuable secondary resources. In this study, a process combining high-gradient magnetic separation (HGMS) with hydrometallurgical methods is proposed to recycle fine-grained Mn tailings. The Mn tailings were treated by HGMS at 12,500 G to obtain a Mn …

Therefore, to extract Mn from manganese oxide ore, MnO 2 must be reduced to a bivalent state. MnO and MnS are acid-soluble and MnSO 4 can be leached by water. Leaching experiments were conducted to evaluate the conversion of MnO 2 to low–valence compounds during roasting. Manganese oxide ore was used as the raw …

Manganese: Nodules, Uses, Facts, Ore, Alloys, Metal
Manganese removes oxygen and sulfur when iron ore (an iron and oxygen compound) is converted into iron. It also is an essential alloy that helps convert iron into steel. As an alloy, it decreases the brittleness of steel and imparts strength. The amount of manganese used per ton of steel is rather small, ranging from 6 to 9 kilograms.
