An experimental study on leaching of cobalt and nickel from a Lubin sulfide flotation copper concentrate with oxygenated sulphuric acid solution in the presence of iron(III) sulfate has been presented. The effect of temperature, iron(III) concentration, initial sulphuric acid concentration, oxygen flow rate and chloride ions addition on cobalt and nickel leaching have been studied. The obtained results show, that enhancing of investigated leaching parameters increases both the rate and leaching recovery of nickel and cobalt. Effect of iron(III) ions concentration is particu-larly significant. Additionally, a significant correlation between copper and nickel/cobalt leach-ing recovery has been observed. Due to the fine dissemination of nickel and cobalt they were observed to leach remarkably faster, when copper leaching recovery exceeded 90%.
