The copper smelting process produces plenty of copper slag every year, which is a hazardous solid waste, but a secondary resource. In the present study, the extraction of copper, nickel, and cobalt from copper slag was investigated through the process of sulfation roasting–water leaching and the process of sulfation roasting–sulfate decomposition …
The plant uses the rainwater that falls on the landfill. This rainwater collects in the leachate treatment facility where any pollutants are removed. Once cleaned, the water is used in the mills for grinding the slag and spent refractories before being pumped back to the leachate facility after the dewatering stage so that it can be cleaned again.
