Investigation of Chemical and Mineralogical Composition of Manganese Ores From Central Asia Deposits

Chemical and mineralogical compositions of manganese ores from Central Asia deposits are investigated. The ores consist of the following minerals: pyrolusite, manganite, psilomelane, hausmannite, magnetite, hydrogoethite, calcite, quartz. Sample ore No.1 is regarded to be rich and quality ore since manganese content in it is approximately 54% and P/Mn ratio equals to 0.002. The given ore is the universal raw material for manganese ferroalloy production.
