There are two main methods for extracting copper ore: open-pit mining and underground mining. Each method is chosen based on the depth and location of the ore deposit. Open-Pit Mining. Open-pit mining is used for copper deposits located near the earth's surface. This method involves removing large quantities of overburden to access the ore below.

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.

Fig. 1. Flow diagram of the copper solvent extraction process. In the extraction units, copper is extracted from the pregnant leach solution to the organic solution. In the stripping units, copper is stripped from the loaded organic solution to the electrolyte solution. The resulting rich electrolyte solution is led to the electrowinning process.

Copper ore is a complex of sulphides of copper, zinc, iron, nickel and minerals of host rocks. For more complete disclosure of copper ore aggregates, it is subjected to grinding to 70% (0.074 mm) at the first stage, obtaining the first copper concentrate ("copper head"), then it is further ground to 90% to a size of 0.043 mm, for subsequent ...

The Mining of Copper: Copper is typically extracted from the ore chalcopyrite (CuFeS 2 ), also known as Copper Pyrites and other sulphide ores. The percentage of copper in these ores is so low that the direct extraction of copper isn't feasible. To extract the copper, we need to concentrate the ore, which is done using the Froth Flotation method.

However, copper and iron were obtained 25.72% and 27.4%, respectively, for a 20% solid-to-liquid ratio. The extraction of copper increases up to 10% of the solid-to-liquid ratio; after that, it will show a decreasing trend. Therefore, the 10% solid-to-liquid ratio was chosen to perform further experiments. The increases in the recovery of ...
