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.

BlastOne : Coal and Copper Slag Blasting Abrasive

All Coal & Copper Slag Abrasive Coal slag is a glass matrix alumina-silicate which is produced as a by-product of coal burning power plants. As it burns, the residual ash becomes molten. When this slag is cooled, it vitrifies into a glassy, abrasive material, which is then crushed to produce blast media. SIZES - Grade: 20-40 Type: Medium

Recover Copper from Reverberatory Furnace Slag

Laboratory and pilot plant investigations have indicated that copper recoveries of 50% can be achieved with fine grinding and flotation of a copper reverberatory furnace slag. Microscopic and microprobe studies indicate that the recoverable copper is in the form of matte, chalcocite, and metallic copper; the percentage of copper in particles appearing to be copper-free was from 0.23 – 0.54% ...
