A geometallurgical comparison between lump ore and pellets of manganese
The difference in manganese content reaches 3.2%. The lump ore from Azul has a Mn/Fe ratio of 13.3, while that of the pellets is 6.8. The low Mn/Fe ratio found in the pellets is the consequence of a significant concentration of Fe, which is not desirable when making some types of alloy.silico-manganese. Silico-manganese was also produced by a number of small-scale ferro-alloy producers. The total production of ferro-manganese in 2015-16 was about 5,18,000 tonnes which remained same in 2016-17.
