pressure oxidation leaching, arsenic and selenium were dissolved into the solution, while copper, tellurium and other metals were oxidized and remained in the alkaline leaching residue. Then copper... of arsenic and antimony can reach over 99.0%. And when the alkaline leaching residue was leached in sulfuric acid solution, the leaching ratios of copper and tellurium can come up to 95.64% and 77.38......
