How copper is extracted from the ores? –
2021-5-7 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.

The Extraction of Copper - Chemistry LibreTexts
2021-6-7 Copper can be extracted from non-sulfide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulfuric acid to produce a very dilute copper(II) sulfate solution. Concentration of the copper(II) sulfate solution by solvent extraction.

Why do we extract copper from low grade ores?
2020-1-30 Bacteria feed on the low grade metal ores and form a solution of copper ions, called a leachate. Slow process - it can take years to extract 50% of the metal from a low grade ore. Energy is needed in the elctrolysis step. Then, the copper will be extracted from the leachate by electrolysis or

Extracting a metal from its ore - chymist
2006-6-27 Copper can be extracted from its ores by reduction. One of the common copper ores, malachite, which is composed of mainly copper carbonate, CuCO3xCu(OH)2, is heated to produce copper oxide with the release of carbon dioxide. CuCO3xCu(OH)2 → 2 CuO + CO2 + H2O The copper oxide is then heated with carbon to get copper. 2 CuO + C → 2 Cu + CO2

From Ore to Finished Product - Copper
2021-7-19 Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.
