Copper Mining And Processing Processing 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 chemical reagents called collectors are added to the slurry and

Copper Mining And Processing Processing Copper Ores

Copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of pure copper called cathodes which will ultimately be made into products for everyday usethe most common types of ore copper oxide and copper sulfide undergo two different processes hydrometallurgy and pyrometallurgy respectively

Chapter 6 Copper Production Technology
