inclusions, as MnO dissolved in the slag, and by production of metal high in silicon and low in carbon. The SiMn production is typically integrated with the manufacture of HCFeMn so that the slag from the HCFeMn production is reprocessed in the production of SiMn. In this way a very high total yield of manganese is achieved. 2.
It is important to fully understand the manganese flow structure to plan for the potential supply-demand imbalance. Material flow analysis (MFA) is a useful tool for resolving this problem (Hao et al., 2017).By qualitatively dividing the life cycle of a specific element or commodity, MFA can trace the element flow route between the lithosphere and society …

With manganese, the only difference is that we're planning on beneficiating the grade of the manganese through a DMS (Dense Media Separation) circuit to increase the purity of the manganese. DMS is a trusted processing route often used in mining and relies on the density of the manganese to separate it from lighter waste minerals.
