COPPER Copper production  TU Delft
COPPER Copper production TU Delft

About 80 of primary copper production comes from lowgrade or poor sulfide ores After rare because these ores are mostly subjected to hydrometallurgical copper recovery for example heap leaching In Zambia and Zaire are used to process such coppercontaining materials as intermediate products eg cement copper or copperI
