Traditional methods. Copper is usually sourced from copper-rich ores in two main methods; Copper can be smelted in a furnace by heating it with air to produce crude copper metal; for example, chalcocite is an ore of copper (I) sulfide, which reacts with oxygen to extract the copper: Cu 2 S (s) + O 2 (g) → 2Cu (s) + SO 2 (g) Copper ore …

This page looks at the extraction of copper from its ores, its purification by electrolysis, and some of its uses. Before you get too bogged down in the extraction of copper, make sure that you need it for whatever syllabus you are using. Extracting copper from its ores. The method used to extract copper from its ores depends on the nature of ...
Purifying Copper. We can purify a solution containing copper, such as copper (II) sulphate, using electrolysis. This involves an impure copper anode and a pure copper cathode. At the anode, copper atoms lose …

Phytomining is the process of using plants to extract copper from low grade ores in the ground. Firstly, areas of land must be found that contain a high concentration of low grade copper ores. Once found, plants are planted on this land and allowed to grow.. As the plants grow they absorb minerals from the ground in which they are growing. This …
