Synergistic treatment and utilization method for non-ferrous smelting arsenic-containing materials

The invention provides a synergistic treatment and utilization method for non-ferrous smelting arsenic-containing materials. According to the method, arsenic sulfide in arsenic sulfide slag in a low-temperature inner cylinder generates solid metal sulfide and gaseous arsenic trioxide; solid arsenic trioxide in smelting smoke dust or oxidized metal mineral powder in a high-temperature inner cylinder is heated to be in a gaseous state; and the low-temperature inner cylinder and the high-temperature inner cylinder are infinitely close to an oxygen-free atmosphere, and carbon powder is input into the high-temperature inner cylinder. The synergistic treatment and utilization method for the non-ferrous smelting arsenic-containing materials has the advantage that various materials are subjected to synergistic treatment, arsenic removal and sulfur fixation, valuable metals in reactants are increased in value through a vulcanization mode, in addition, sulfur in the reactants is reserved, and subsequent pyrometallurgy
