How to Refine Gold: 2 Major Techniques of Gold Refining Process
Mostly, the gold obtained through gold electrolysis is usually very pure, almost %. In fact, this procedure is the best method for processing gold with the highest karatage (24 Karats = 100 percent gold). This is why gold electrolysis is very common in countries where pure gold pieces are given priority over the ones with low karatage.
