has gained a leading market share of new copper solvent extraction capacity. The VSFTM Solvent Extraction technology VSFTM technology is the result of the continuous development of mixer-settler technology. It has been designed to run at minimum operating costs, ensuring high profitability even during times of copper price fluctuations.

Reduction in plant operating costs; Improved copper cathode income due to an improved leach recovery of about 1 to 1.5% above conventional milling; ... "This is largely due to the fact that copper extraction using solvent extraction technology generates a high acid raffinate stream – which you can recycle to the milling area," confirms ...

This chapter describes the investment and production costs of producing copper metal from ore and discusses how these costs are affected by such factors as ore grade, …

Reason to smile. First Quantum's Kansanshi mine in Zambia is expected to produce 220–235kt of copper, and 120–130koz of gold in 2020. Image: FQM

The following is a process of copper extraction from chalcopyrite ore into pure metal. While oxide ores can be processed using pyrometallurgical techniques, hydrometallurgical methods are more cost effective. The copper ore is crushed and ground before it is concentrated to between 20 and 40% copper in a flotation process.
