Abstract
The factors of leaching temperature,time,granularity,oxygen partial pressure and sulfuric acid concentration are studied on the leaching rates of Zinc and Iron.The results show that the Zinc leaching rate can reach 93% after 3 hours under the condition of 100 ℃,400 kPa oxygen pressure.At the same time,Indium can be leached too.
