Our gold refining process begins when we receive your scrap gold or other precious metals to be recycled. To determine the metals purity we perform an assay. Once we have assayed the weight and purity of the gold we have all the information we need to quote you a payout price. From there your gold is melted down in our refinery.
This is a free tutorial on gold recovery method using nitric acid to extract pure gold from old gold and scraps of gold by process of dissolving unwanted metals. When I use this refining method I regard the purity of the gold as 22kt and I alloy it accordingly down to 18kt or 14kt. This gives me a safety margin so the gold is a slightly .
The invention provides a cathode gold electrolytic refining process. According to the invention an electrolyte formula is changed and electrolytic refining is carried out in a hydrochloric acid system with low gold ion solubility Au 3 80-120gL and low acid 60-90gL with a titanium motherboard used for replacing a traditional gold starting sheet as a cathode.
Before gold and other precious metals can be converted into jewelries and used for various other purposes. They have to go through a refining process to get them into a useful form.
