Copper Mining and Processing: Processing of Copper Ores ...

After the copper ore is crushed, liquid is added to make it a slurry. The slurry is a mix of valuable copper ore minerals and "worthless" rock, called gangue (pronounced "gang"). The slurry is placed in a tank and a process called froth floatation is used to separate the copper minerals from the gangue.

The present study focused on the reprocessing of copper and nickel from mine tailings. In this work, recovery of copper and nickel from mine tailing by combined process of flotation and high pressure oxidative leaching were considered. In the first stage, effects of flotation parameters including collector type, collector dosage, and pH and pulp density were examined.
