Beneficiation occurs as a first and second stage process:1. Refining mined ore by crushing, screening and jigging (mechanical) into refined ore;2. Reducing ore to a metal alloy by smelting and reduction processes (chemical).
The major commercial use of manganese ferro-alloys is in steelmaking.Manganese ferro-alloys produced commercially can be divided into the following four categories:
High-carbon Ferromanganese (HCFEMN)
Refined Ferromanganese (MCFEMN)
Silico Manganese (SIMN)
Low-Carbon Silico Manganese (LCSIMN).
To produce manganese ferro-alloys, a carbothermic reduction process is followed in which manganese-bearing minerals are reduced by solid carbon reductants to produce an alloy, slag, and off-gas.
The two main cost drivers for the production of manganese ferro-alloys, apart from ore, are the price of reductant and the price of electricity.
In Southern Africa, only saf technology is applied in the production of manganese ferro-alloys. In other parts of the world, HCFEMN is also produced using blast furnace technology. The furnaces can be open, semi-open, or closed, depending on the environmental regulations of each specific country. The furnaces can be stationary or rotating. Typically production furnaces carry loads of 15-45 mw, and at this size the furnaces are always stationary. In Southern Africa the installed capacities range from6 mva to 81 mva (estimated as 4.4 mw and 50 mw).
We are currently adapting a small, mobile, thermite-based beneficiation process, as is utilized in Zambia and by independent Chinese companies in rural areas. The process utilizes thermite as burning agent, aluminium as catalyst, and use no furnace or cathode / arc technology, in order to produce Ferromanganese with little or no electricity required. The process is a low technology, small scale process and limited to producing 5 000 mt of Ferromanganese per month.
