10/10/2015· However, among the various processing method, physical separation by froth flotation is widely applied and some researchers considered flotation as an effective method to recover copper from slag. Understanding the slag mineralogy and associations of copper in the flotation feed is crucial to optimise operations.
30/11/2008· 1.. IntroductionLarge quantities of waste materials such as copper slag are produced as a by product of industrial operations. The extraction of copper from sulphide ores is usually carried out within a pyrometallurgical process route, which involves the mining activities and concentration of the ore often via flotation followed by smelting and refining operations to
08/02/2017· Consequently, flotation was attempted to recycle Cu in slag containing copper sulphide components. Three key factors affecting flotation were ascertained, namely, grinding fineness, the collector and the pH value, while the recovery of Cu estimated by ICP and XRF.
slag, together with an optimization on the flotation reagents. Fan, Li, Wei, Li, and Sun concluded that three factors affect CS flotation: particle fineness, collector type, and pH. They achieved a concentrate with a copper grade of 14,47% and copper recovery of 79,66%, by milling 80% under 74 µ m,
The pyrometallurgical production of copper generates slags, a residue with a signiﬁcant content of this. metal. Copper can be recovered from the slags by
03/02/2021· Furthermore, flotation produced a discard tailing that was lower in copper content than the 0.5 percent reverberatory slag usually discarded. Flotation of Copper from Water Quenched Converter Slags The test procedure employed in the flotation of copper from slags remelted in the induction furnace and water quenched was identical with the procedure for
For an air cooled slag at optimized conditions, 72% of copper was recovered in one stage flotation and a 12.6% copper concentrate was achieved. The best recovery efficiency was obtained when 30 g...
1 · Moreover, the flotation kinetic model of copper slag was established and the results showed that the movement of copper slag in the flotation process conforms to the first order kinetics. The addition of sodium carbonate increased the stability of the pulp and improved the flotation kinetics greatly, resulting in a better flotation performance.
