view moreSince inception of the mine, refractory ore from the copper production process was surface stockpiled. KCM has now developed a process to extract copper from the refractory ore stockpile. The company also produces several by-products, including sulphuric acid produced from the smelting process, which is largely consumed in the leaching process.
view moreThe pyrometallurgical production of copper from sulfide concentrates is a journey involving the gradual oxidation of copper concentrates in sequential steps. These steps are smelting, converting, and refining. The overall copper making process can be explained by using the copper–oxygen–sulfur predominance diagrams.
