Collaborative treatment and comprehensive utilization technology of copper containing sludge combined with heating solid waste
This article introduces the technology of co-processing copper containing sludge and heating solid waste using oxygen enriched side blown melt pool smelting furnace.This technology can fully utilize the characteristics of melt pool smelting and recover valuable metals such as copper.This process has a high metal recovery rate and produces water quenched slag as general solid waste,achieving comprehensive resource recovery and harmless treatment of hazardous waste.The results show that an annual processing capacity of 100000 tons of copper containing solid waste produces approximately 4000t/a of polymetallic alloys,including 55%copper and 11.9%nickel.Main process technical indicators:The direct yield of copper element is 90%,the direct yield of nickel element is 70%,and the coal yield is about 22%.
