Manganiferous Iron Ore Chlorination

The manganiferous iron ore consisted mainly of hematite, magnetite, goethite, and quartz with minor quantities of stilpnomelane, minnesotaite, and chlorite. The manganese minerals identified were manganite and a minor quantity of pyrolusite. The ore was ground in a pulverizer to minus 100 mesh prior to chlorination.get price

Newbery–Vautin chlorination process Wikipedia

The Newbery–Vautin chlorination process is a process to extract gold from its ore using chlorination developed by James Cosmo Newbery and Claude Vautin. Background. The process of extracting gold from ores by absorption of the precious metal in chlorine gas, from which it is reduced to a metallic state, is not a very new discovery. It was first introduced by Karl Friedrich Plattner aroundget price
