- Granulation Plant For Copper Slag
In the present paper, recovery of valuable metals from copper smelter slag of Balkhash copper plant (Kazakhstan) was investigated. To recover Fe, Zn and Cu to water-soluble form, the mixture of 150 g of copper slag and 60 g of 85% sulfuric acid was granulated and then roasted in the temperature range of 473–643 K (200–370 °C) …
