<p>An oxidized liquid slag coming most of ten from prior metallurgic operations and still containing from 10 to 40% of manganese as MnO, is treated, under stirring, by a reducing alloy based on silicium (silicium content at least equals 60% and, preferably, at least 70%). A slag substantially depleated of manganese is obtained and a metal containing more than 60% and, usually, more than 70% of manganese, and from 5 to 40% and preferably from 10 to 35% of silicium is provided. </p> |
