Agitation　leaching　is　a　promising　technology　in　hydrometallurgy　for　treating　copper–cobalt　oxide　ores.　In　this　work,　the　behavior　of　oxide　ores　containing　around　2.3%　Cu　and　0.3%　Co　received　from　Congo　was　investigated　for　varying　particle　size,　acidity,　pulp　density,　temperature,　leaching　time,　and　reduction　potential.　XRD,　optical　microscopy　(OM),　and　ICP-OES　methods　were　used　to　examine　the　chemical　composition,　morphology,　and　metal　content　of　the　samples.　The　copper　and　cobalt　recovery　reached　88.2%　and　82.5%,　respectively,　at　room　temperature,　with　a　leaching　time　of　4　h,　a　pulp　density　of　33%,　an　acidity　of　178　g/L,　and　no　reductant.　The　Cu　and　Co　remaining　in　the　leaching　residue　were　found　to　be　in　their　sulfide　forms　and　coated　with　dense　and　fine　calcium　sulfate.　To　improve　the　metal　recovery,　a　combination　of　flotation　and　agitation　leaching　of　the　flotation　tailings　method　was　adopted,　after　which　the　Cu　and　Co　recovery　reached　96.6%　and　86.0%,　respectively.　©　2023　by　the　authors.
