Ordinarily too brittle to be of structural value itself, it is an Manganese is an essential element for modern industrial societies. Its principal use is in steelmaking, where it serves as a purifying agent in iron-ore refining and as an alloy that converts iron into steel. Although the amount of manganese consumed to make a ton of steel is small, ranging from 6 to 9 kilograms, it is an irreplaceable Manganese U.S. Geological Survey USGS.gov

Impact of open manganese mines on the health of children
Abstract. Introduction: Chronic manganese (Mn) exposure is a health hazard associated with the mining and processing of Mn ores. Children living in an area with increased environmental exposure to Mn may have symptoms of chronic toxicity that are different from adults who experience occupational exposure.Abandoned tailings are one of the important sources of heavy metal pollution in regions surrounding mining areas. In this study, the speciation and kinetic characteristics of Mn and Pb were analyzed in waste rocks from a manganese mining area. The results show that under different experimental conditions, Mn mainly occurs in the Mn and Pb in Waste Rocks from Manganese Mining Areas

Manganese Mining and Extraction Manganese Mining Processing
Most underground mining of the manganese is generally done by room and pillar method. Mining at Nchwaning and Gloria mines uses two shafts when it was initiated in 1981, one vertical hoisting shaft that is 450m deep and another vertical shaft. Now further rooms and pillar rooms are made with low grade ore for easier mining.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].
