Utilisation of copper slag for cement manufacture

01/05/2007· Leaching studies of copper from copper slag admixed concrete: 10x10x10cm 3 concrete cubes with water to cement ratio of 0.44 were cast using copper slag. After 24 hours, the mortar specimens were demoulded and kept immersed in various aqueous media such as tapwater, rainwater and sea water. Periodically copper leaching is estimated using AAS. The results of the study are

How to Refine Copper Cement 911 Metallurgist

29/06/2019· Cost estimates were made for processing cement copper by the copper powder and sintered anode electrorefining processes described. Because smaller plants probably would be more interested in producing copper powder than installing expensive electrorefining facilities, the powder process was evaluated for a plant having a capacity for producing 10 tons of copper powder per day.

Utilization of copper slag in cement and concrete

01/08/2008· The use of copper slag as a pozzolanic material for a partial substitute for ordinary Portland cement and its effects on the hydration reactions and properties of mortar and concrete have been reported in several publications (Al-Jabri et al., 2006, Taha et al., 2007, Malhotra, 1993, Tixier et al., 1997, Ariño and Mobasher, 1999, Douglas and Mainwaring, 1986, Deja and Malolepszy, 1989).
