Abstract Scope Copper smelter slag were leached using sulphuric acid solutions under the condition of the atmosphere. Base on the composition and phase of copper slag, the effect of the concentration of sulfuric acid and leaching temperature to the leaching degree of Fe, Cu, Co and Ni in the copper slag were investigated in this paper. Simultaneously, the influence of sulfuric acid concentration, leaching time, leaching temperature and the amount of sulfuric acid(solid-liquid ratio) to the leaching rate of these metal elements were researched. Experimental results showed that: with the increasing temperature, the dissolution rates of the metals elements increased first and then decreased. Due to the influence of silica gel which was obtained in beginning of leaching, the higher the concentration of sulfuric acid is not conducive to dissolution of the valuable metal elements. The dissolution degree of Fe, Cu, Co and Ni were 92.83%、96.76%、93.62% and 63.41% respectively.
