Dissolution of copper and iron from malachite ore and ...

2014-3-1  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.

2021-11-22  Copper ore is a vein of green copper carbonate embedded in granite. Gains malachite chunks when mined. Be careful, because certain ores require special tools for successful mining of the mineral. If improper tools are used, the mineral is lost. Further processing in the furnace is required to extract pure copper from the carbonate. Copper Ore blocks are only obtainable in Creative mode.
