At Vista Gold's Mt Todd gold project in Australia the combination of XRT and laser-based ore sorting has shown a coarse fraction (+16 mm) high pressure grinding rolled product can efficiently be separated into waste and ore piles. The laser sensor, in this case, detects quartz in the ore after it has already gone through an XRT-based process.

Most methods of removal rely on the oxidation of Mn (II) to Mn (IV) to precipitate out the manganese for subsequent removal through a filter bed of sand. Precipitation is typically achieved by adjusting the pH to 7 and chlorinating to ensure a residual of chlorine downstream of the filter. The capital cost of these system based on sand beds can ...

Manganese is used in the manufacture of all steel, in the proportion of about 14 pounds of metallic manganese per ton of steel. Nearly 95 percent of all the manganese consumed is used in this way. Manganese is not utilized in this case as an alloy, but as a remover of deleterious oxygen and, to some extent, of sulphur, in the steel-making process.
