In this paper, copper and cobalt from purple ore are used as raw materials, a direct acid leaching method is used to recycle copper and cobalt, and the effects of such process parameters as fineness, leaching temperature and stirring speed on the leaching rate of copper and cobalt are explored. Under the optimum leaching condition of no grinding, leaching temperature of 70 ℃, stirring speed of 400 r/min, liquid-solid ratio of 4:1, mass concentration of sulfuric acid of 160 g/L and leaching time of 4 h, the leaching rates of copper and cobalt are 72.16% and 70.81% respectively. The chemical phase analysis of copper and cobalt shows that the mass fraction of copper sulfate in purple ore is the highest, and the mass fraction of secondary copper sulfide is the lowest. In sulfuric acid system, copper sulfate and free copper oxide are easier to be leached. Cobalt in purple ore mainly exists in such form as cobalt sulfate, cobalt ferrite and tricobalt tetraoxide, as well as a small amount of cobalt sulfide and cobalt oxide. In sulfuric acid system, cobalt sulfate and cobalt sulfide are easy to be leached, but tricobalt tetraoxide and cobalt ferrite are difficult to be leached.
