Electrowinning Copper Chemistry Tutorial

Electrowinning Copper Key Concepts. Electrowinning refers to the process of using electrolysis to extract a metallic element from the compounds in its ore. Copper occurs on Earth both as native copper (the uncombined element, Cu), and in ores (copper compounds, or mixtures of compounds, from which copper metal can be extracted profitably). Copper ores are usually copper oxides, copper sulfides ...

Aqueous copper and nickel ions are produced at the anode, and pure copper metal is isolated at the cathode. The experiment is a visually appealing illustration of the process of electrorefining using selective reduction. The experiment requires a 6-V battery (or high-current power supply), appropriate patch cords, 6 M HCl, and a 250-mL beaker. Using a current of approximately 1 A, an easily ...

Copper refining

Purification of copper is achieved by electrorefining. Large slabs of crude copper serve as the anodes in the cell, and thin sheets of pure copper serve as the cathodes. The Amarillo refinery houses 2,400 tanks in a single building. The electrolyte consists of an acidic solution of CuSO 4. Application of a suitable voltage to the electrodes causes oxidation of copper metal at the anode and ...
