Review on Copper HydrometallurgyThe current technological challenges mean that engineers are expected to apply the available extraction in the field of extractive metallurgy. Extraction of copper, one of the most used metals, has been practiced since ancient times around the world. Three crucial steps, namely sulphide roasting, leaching of ores and concentrates, and electro extraction through solvent extraction, are described here with ample details, diagrams, examples and
