Abstract
A method for treating tin-containing materials, which consists in that the tin-containing materials are previously mixed with a solid carbonaceous reducing agent and with lime flux, the obtained melt charge is then charged in an electric furnace in which it is made melting with reduction, the tin metal being intermittently bled as it accumulates in the furnace, characterized in that the fusion with reduction of tin-containing materials is carried out in a bath of molten iron slag, the melt charge being continuously charged in the area near the electrode, scaring the content of said solid carbonaceous reducing agent, in said melting charge, so as to ensure the reduction of only tin, the consumption of lime flux being such that it is obtained from 12 to 24% by weight of calcium oxide in the final slag, the ferrous oxide content being 30 to 8% by weight, respectively; after melting the required amount of the melt charge, determined the upper level of the molten slag bath, the iron slag is partially bled from the furnace, with prior tin exhaustion of the iron slag in the furnace, and subsequent treatment of said slag to waste slag, by any usual method.
