Dissolution of copper and iron from malachite ore and

The present work describes an investigation of a chemical process for the recovery of copper and iron from malachite ore. For the dissolution of copper and iron, H 2 SO 4 was employed as well as H 2 O 2 as an oxidizing agent. The effects of reaction temperature and time, acid concentration, liquid to solid ratio and agitation rate on the copper and iron percentage were investigated.
