Quality requirements of the metallurgical industry of manganese ore is very high.
For steel-making pig iron, manganese pig iron, spiegeleisen iron ore, iron content is unrestricted, the total content of manganese and iron ore is best to achieve 40% ~ 50%.
Manganese content of the ore and ferromanganese smelting of various grades of manganese alloys, the ratio of certain requirements.

Low-carbon ferromanganese smelting ore manganese content of 36% to 40%, manganese than 6 to 8.5, phosphorus manganese 0.002 to 0.0036; carbon ferromanganese smelting, ore manganese content of 33% ~ 40%, manganese than 3.8 to 7.8, phosphorus manganese 0.002 to 0.005; smelting manganese-silicon alloys, ores manganese content of 29% ~ 35%, manganese 3.3 to 7.5, phosphorus manganese than 0.0016 ~ 0.0048; blast furnace ferromanganese ore manganese content of 30 %,manganese from 2 to 7, phosphorus manganese than 0.005.

Hammer Crusher of Liming heavy industry has many good function，it can meet the need of the  exploitation   in manganese ore in India.
