发明名称 VERFAHREN ZUM WIEDERVERWERTEN VON ABFALLSTOFFEN DER MESSINGGIESSEREIEN
摘要 <p>A recycling process for zinc-rich solid waste containing zinc oxide, Cu oxides and impurities normally present in brass, in which a mixture is formed containing the waste with a finely divided solid reducing agent and a binder, and the mixture is compacted as agglomerates with open pores. The agglomerates are added into a treatment reactor containing a bath of liquid copper or brass metal, in which the zinc and copper oxides are reduced, to obtain in the treatment reactor after the reduction, a new brass in liquid form and a new waste. The new liquid brass is transferred into a fusion and casting furnace, in which its composition is optionally adjusted, and the new liquid brass is cast to form a product. Any waste present in the treatment reactor and the casting furnace are recycled using this process.</p>
