During the electrolysis process, copper atoms leave the copper sulfate solution and form a coating on the anode, leaving sulfur residue in the electrolytic solution. Given the stable and readily available nature of copper sulfate, it makes an inexpensive school laboratory material and eliminates the chlorine gas risk associated with electroplating solutions.

This is a common extraction process for the more reactive metals for example, for aluminum and metals above it in the electrochemical series. You may also come across it in other cases such as one method of extracting copper and in the purification of copper. During electrolysis, electrons are being added directly to the metal ions at the cathode (the negative electrode). The downside ...

In contrast to salar brine sources, extraction of lithium from spodumene, lepidolite, petalite, amblygonite, and eucryptite requires a wide range of processes. Because of the amount of energy consumption and materials required, lithium production from mining is a much more costly process than brine extraction, even though these minerals have a higher lithium content than the saltwater.
