Abstract

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.
