Gold Electrolysis | Electrolysis Machine | Gold Refining

The high temperature and high-pressure desorption method is to install the gold-loaded carbon in a pressure vessel, and mix the solution with 0.4% to 1% NaOH and 0.1% NaCN, heat temperature to 130 to 160 ° C, under the pressure of 3.6 to 5.9 kg/cm2. Within 2 to 6 hours, the gold and silver desorption rates of gold-loaded carbon exceeded 90%.

High Karat Gold (21K-23K) - Refining and Melting. Pt. 1

In this current gold refining process we will dissolve the high gold alloy directly in AR leaving a solid AgCl residue at the bottom, then separate the liquid gold solution (HAuCl4) by means of filtration. Few things to consider before choosing this process for high gold content alloy. This process is applicable as long as silver content is below 10%. 22K gold jewelry usually holds 5% silver

How to Refine Gold: 2 Major Techniques of Gold Refining

It is an electrochemical process which has been applied in many large-scale gold-refining establishments or industries. The principle of gold electrolysis is very straightforward or simple: Dore bar, which is a cast gold ingot at 95% plus purity is used as the anode. The cathode (s) for this electrochemical procedure are small sheets of 24 Karat (pure) gold sheeting. When current is applied

Process Of Refining Gold | My Gold Guide

2018-05-15· This requires three main components: Anode (made with Gold that needs refining), Cathode (made with 24-karat gold), and an Electrolyte solution. Once the anode and cathode are suspended in the electrolyte solution, an electric current is passed through it. This causes all gold to travel from the anode to the cathode. All the impurities get dissolved in the solution. At the end of this process
