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.

Manganese is one of the leading mining pollutants. ... Enzymes like peroxidases, laccases, etc. show better results in the biological remediation process, and these enzymes can easily be monitored, handled, and controlled. These enzymes possess many advantages and help in less waste production, less toxicity, and the ability to …
The mining and ore processing of sulfide-bearing deposits generates large volumes of waste rock (WR) and tailings, which often contain barren and residual iron sulfides (e.g., pyrite and pyrrhotite). ... Results show that for all the studied sulfides, oxidation by ferric iron produces more acidity than oxidation by oxygen. Table 1. …
