There are two main types of electrolytic processes, called electro-refining and electro-winning. Both processes use direct electrical current whereby pure metal is deposited at the cathode. Electro-refining is the preferred method as an electrolytic process for gold and other precious metals.

Sure it's possible, it just isn't practical. First off you have to set up a cell, a fizzer cell is one option, to make your gold chloride electrolyte, you will have to commit the gold in solution to stay in solution for the useful life of the cell, until the impurities rise to the level at which you have to refine the electrolyte and start over.
