铜冶炼过程多型固废整体回收新技术

重点介绍了铜冶炼过程多相态富集分离新技术,实现冶炼过程多型固废的定向富集和整体回收。将铜冶炼厂产出的阳极泥还原熔炼渣、文丘里泥、银硒渣、二次沉硒物、铅滤饼、冶炼烟尘浸出渣、废铅阳极等多类型固废合并冶炼。通过从多金属合金相中回收金、银、铅、铋,从多相态富集分离炉洗涤液中回收硒,从多相态富集分离炉烟尘中回收碲及三氧化二锑,实现不同目标元素在各相中的富集和分离。新技术具有物料适应性好、回收金属种类多、金属综合回收率高、环境友好等特点。

New Integrated Technology to Recover Multi-type Solid Wastes in Copper Smelting

A new technology of multi-phase enrichment & separation in copper smelting were introduced. Orientation enrichment and entire recycle of multi-type solid wastes was realized. Multi-type solid wastes from copper smelter, i.e, anode slime reducing smelting slag, Venturi slime, Ag-Se slag, secondary selenium sediment, Pb filter cake, smelting fume leaching residue, waste Pb anode, were combined-smelting. Different objective elements in various phase are enriched and separated through recycling Au, Ag, Pb and Bi from multi-metal alloy, recovering Se from washing solution of multiphase enrichment and separation furnace (MES Furnace), and recovering Te and Sb2O3 from fume of MES Furnace. New technology has advantages of good adaptability, variety metal species recycled, high metal comprehensive recovery, and environment friendliness.
