Copper Recovery by Solvent Extraction Techniques
For cement copper production freight and smelting charges alone usually exceed this figure. In addition, acid consumption in the cementation process exceeds that in solvent extraction/electrowinning by about 1.5 tons for every ton of copper extracted and it is possible for the consumption of iron to be as high as 4 tons per ton of copper.

COPPER HYDROMETALLURGY AND EXTRACTION FROM …
Copper extraction with trialkyl amines rises when the acidity of the aqueous phase and the chloride content increase. Thus, the stripping is possible with solutions of low acidity and low chloride concentration. Chelating agents, such as hydroxyoximes and P-diketones extract copper

How copper is extracted from the ores? – Restaurantnorman
Copper can be extracted from its ore by: Underground: sinking a vertical shaft into the Earth to an appropriate depth and driving horizontal tunnels into the ore. This trickles slowly through the ore dissolving copper to form copper sulfate. The copper is recovered by electrolytic refining.

Along with the copper extraction, iron (29.6 wt%), aluminum (70.2 wt%), magnesium (85.4 wt%), and calcium (44.4 wt%) were also leached out considerably through the dissolution of silicate and carbonate gangue minerals. In this study, an 80.0–94.26% copper extraction rate with reduced acid consumption (20%) proved to be a cost-effective approach.

A gradual increase in copper extraction was noted when the temperature was increased from 100 to 160 °C, during which a temperature increase of 20 °C, accordingly yielded an increase of about 20% in copper extraction. However, a further increase in temperature to 180 °C, did not yield a significant improvement in copper dissolution.
