| Abstract: | Large amounts of non-ferrous slags containing Co, Ni, and Cu are produced and stockpiled by metallurgical industries. These industries also produce sulphur dioxide, an air pollutant. Using sulphur dioxide as a leaching reagent to leach the valuable metals from slag would reap both economical gains and environmental benefits. Extraction of these metals using aqueous sulphur dioxide (SO2(aq)) is being carried out in our group. |
