Electrochemistry: Electrolytic refining of aluminum

Feb 11, 2011· Electrolytic refining of aluminum Aluminum is present in most rocks and is the most abundant metallic element in the earth's crust (eight percent by weight.) However, its isolation is very difficult and expensive to accomplish by purely chemical means, as evidenced by the high E° (–1.66 v) of the Al 3+ /Al couple.

Electrorefining - Purifying Copper in Industry - Activity

An impure sample of copper may be purified by using the sample as the anode in an electrolysis cell with a pure copper cathode and copper(II) sulfate solution as the electrolyte. In this activity, we first examine the behaviour of an electrolytic cell in which both electrodes are made of pure copper.
