Copper Mining Info. Then the leach solution containing the dissolved copper is subjected to a process called solvent extraction (SX). The SX process concentrates and purifies the copper leach solution so the copper can be recovered at a high electrical current efficiency by the electrowinning cells.

Effect of Pretreatment on Leaching Primary Copper Sulfide

This study considers accelerating chalcopyrite dissolution by pretreating the ore before leaching, using a longer repose time and shorter leaching time. This has been done before with copper oxide ores and secondary copper sulfide ores . With copper oxide, agglomeration and acid curing process are commonly used before leaching.

Technological conditions and kinetics of leaching copper

Abstract. During this process, the chemical reaction is the control step, and the reaction order of H 2 SO 4 is 0.433 84. The third stage is the leaching of copper oxide wrapped by hematite-limonite and silicate ore with apparent activation energy of 16.08 kJ/mol, which belongs to the mixed control.

COPPER Copper production TU Delft

Sulfidic copper ores are too dilute for direct smelting. Smelting these materials would require too rare because these ores are mostly subjected to hydrometallurgical copper recovery, for example, heap leaching. In Zambia and Zaire, however, are used to process such copper-containing materials as intermediate products (e.g., cement
