从某冶炼厂水淬铜炉渣浮选回收铜的试验研究

Tests on Copper Separation in Flotation from Copper Slags of a Smelting Plant

论述了造锍熔炼过程、炉渣冷却方式及冷却速度、炉渣物质组成对炼铜炉渣浮选回收铜的影响,并指出熔融炉渣的冷却方式及冷却速度是影响铜炉渣浮选回收铜的主要因素。以水玻璃为分散剂和抑制剂、丁基黄药和P3为组合捕收剂,对国内某铜冶炼厂水淬铜炉渣中的铜进行浮选回收,在-320目占90%的磨矿细度下,获得了铜精矿铜品位为17.08%,铜回收率为56.98%的试验指标。

The Influence factors of the matte smelting process, slag cooling method, cooling rate and slag composition on copper recover）, in flotation are discussed. It is pointed out that slag cooling method and cooling rate are the main factors that affected the flotation recovery from copper slag. Taking sodium silicate as dispersant and inhibitor, and butyl xanthate and P3 as combinatorial collector, experiments on flotation recovery of copper from copper slag for a domestic copper melting plant are made. Under grinding of 90% -320 mesh, a copper concentrate grading 17.08% at a 56.98% copper recovery was obtained.
