1. Grinding: crush and grind the copper ore into fine powder so that it can better contact with the organic solvent.

2. Leaching: mix the ground ore with the organic solvent, and the copper will dissolve in the organic solvent at a certain temperature and pressure.

3. Extraction: the organic solvent in which the copper is dissolved comes into contact with water, so that the copper is transferred from the organic solvent to the water.

4. Stripping: add another organic solvent to the copper-containing aqueous solution to extract the copper from the water.

5. Distillation: separate the organic solvent from the mixture by heating to obtain high-purity copper.

The organic solvent used in the copper extraction process has the characteristics of high specific gravity, high viscosity, high chemical stability, and good wettability, solubility and permeability. At the same time, in order to improve the extraction efficiency of copper, some additives are also used to adjust the properties of the solvent and improve the effect of the extraction process.

The development direction of copper extraction technology mainly includes improving the performance of the extractant, optimizing the extraction process and increasing the recovery rate of copper. In addition, in order to meet environmental protection requirements, low-pollution, high-efficiency and energy-saving copper extraction technology is developed.
