anode containing 6210 copper, figured for the solution of copper. The cathode weighed 17.585 grams at the beginning of electrolysis and 56.632 grams at the end, a gain of 39.047 grruns.

The blister copper is already virtually pure (in excess of 99% copper). But for today's market, this is not really pure enough! It is purified further using electrolysis. This is known as electrolytic refining.. The blister copper is cast into large slabs which will be used as the anodes in the electrolysis apparatus (see page 4).The electrolytic refining of copper produces the high quality ...

Electrolysis of copper transfers copper atoms from an impure copper anode to a pure copper cathode, leaving the impurities behind. Unrefined copper is about 99 % pure. It contains traces of metals such as Fe, Zn, Ag, Au, and Pt. The purity can be increased to 99.95 % by electrolytic refining in a cell similar to that shown below. A thin sheet of high-purity Cu serves as the cathode.
