Unearthing hidden value using pre-concentration …

The low-grade sections of the ore body were blasted less intensely, so the waste was preferentially distributed to coarse fragments. The ore was then mined, crushed and screened so that the finer, higher-grade particles reported to the processing plant; whilst the coarser, lower grade material reported to waste. This achieved a higher feed grade to the processing plant (Source: https://www ...

Production of Ferro- Manganese – IspatGuru

19/06/2018· An artificial Mn ore produced as a high grade ore is particularly suitable because of its low impurity level and because all the Mn is present as MnO. The reduction of the higher oxides of Mn is therefore unnecessary. The typical consumption figures per ton of low C Fe-Mn ferromanganese having composition of Mn – 85 % to 92 %, C – around 0.1 %, and Si around 1 % with a manganese recovery ...
