Electrorefining uses a similar process to remove impurities from a metal. Both processes use electroplating on a large scale and are important techniques for the economical and straightforward purification of non ...Production and Electrolysis of Light Metals | ScienceDirectAn X-ray radiographic technique has been employed to study the behaviour of the three phases: anode gas, bath, and aluminium, in a laboratory aluminium electrolysis cell. Experiments in which small particles (1–2 mm) of TiB 2 were placed at the bath - metal interface show that the particles can move along the interface when current is applied.
