In this paper, the influence of different process parameters (leaching agent concentrations, solid phase concentrations and temperatures) on the degree of cobalt leaching was investigated. It was found that the maximum degree of cobalt leaching (about 100%) is achieved at the following process parameters: sulfuric acid concentration was 3 mol/dm3, solid phase concentration was 33 g/dm3, volume flow of sulfur dioxide was 2 dm3/min, temperature was 85°C and leaching process duration was 60 minutes.enLiCoO2leachingsulfur dioxideconferenceObject
