FIELD: ferrous metallurgy.
SUBSTANCE: metallic manganese is produced from the total mass limit phosphorusless manganese slag produced in reducing manganese oxide and silicon oxide in the slag by metallic reduction. The manganese oxide begins to reduce by aluminum supplied to the slag and finishes by silicon which is reduced from the silicon oxide in the slag by aluminum parallel to the reduction of the manganese oxide. In so doing, the dump slag is produced, which contains mainly the oxides of aluminum and silicon.
EFFECT: improved ecology.
