Abstract:In order to improve copper-cobalt recovery rate from copper-cobaltoxide during the hydrometallurgical process，the technological process of acid leaching, CCD, copper SX and FAM removal process are analyzed. Solutions of improving copper-cobalt recovery rate are pointed out according to the main factors which restricting the recovery rate of copper and cobalt. Practice shows the recovery rate of copper and cobalt can be significantly improved by selecting suitable leaching methods, washing methods, setting extra low-grade copper SX process and taking low concentration SO2 gas as FAM removal reagent.
