and tellurium were leached in sulfuric acid solution. The base metals containing in copper anode slime can be removed efficiently. The result shows that valuable metals cannot be separated effectively whether the direct leaching was performed in alkaline solution or sulfuric acid solution. Arsenic and antimony cannot be removed together under different oxidation methods when the process of alkaline......
