29/7/2019· The iron minerals are always found as an impurity in all kinds of manganese ores; however, these are successfully removed using variety of magnetic separation processes. Carbonate ores are mainly found in Ukraine, China, and South Africa and these ores are upgraded primarily by gravity and magnetic separation process.

UPGRADING OF Mn / Fe RATIO OF LOW-GRADE MANGANESE

Low-grade manganese ore is first crushed to the grain size of -15 mm, depending on the characteristics of the ore, to create proper conditions for the next phase. After crushing, the ore is charged with coke or coal in a rotary kiln. In the rotary kiln, iron components are reduced mainly to magnetite at a temperature of 700 – 1000 °C.
