What are some ways to extract copper from copper oxide?

Impure copper is purified by electrolysis in which the anode is impure copper, the cathode is pure copper and the electrolyte is copper sulphate solution. An alloy is a ... For example, copper is formed if copper oxide is heated strongly with charcoal, which is mostly carbon: copper(II) ... read more

One way would be transforming the copper oxide into the sulphate through treatment with sulfuric acid and then electrolyzing the solution to plate the copper onto a substance that can be removed or pure copper. read more

Extraction and purification of copper. Copper is less reactive than carbon, so it can be extracted from its ores by heating it with carbon. For example, copper is formed if copper oxide is heated strongly with charcoal - which is mostly carbon: copper oxide + carbon → copper + carbon dioxide. Copper is purified by electrolysis. read more

Copper can be lost from the matte in three ways: as cuprous oxide (Cu 2 O) dissolved in the slag, as sulfide copper dissolved in the slag or as tiny droplets (or prills) of matte suspended in the slag. read more
