ABSTRACT:
Powdered FeMn alloy is leached with liquid bismuth, which alloys preferentially with the manganese to form liquid BiMn alloy, leaving behind iron powder. The BiMn is then electrorefined; an anode 1 selectively ionises the manganese, which is carried to the cathode 3 where it is reduced to the metal and collected in a stream of molten aluminium as AlMn master alloy.
