  • How to Extract Gold with Electrolysis Bing

    How to Extract Gold with Electrolysis Bing

    Using Electricity as a Method of Gold Extraction One hundred grams of 100 mesh ore were placed in a jar with 500 grams of water and 15 grams of sodium chloride. This was electrolyzed with a current of 0.3 – 0.6 ampere for three hours, current density 0.1 – 0.2. The electrodes were of platinum and the solution was slowly agitated.

  • Electrolytic recovery of gold from aqueous solutions

    Electrolytic recovery of gold from aqueous solutions

    Oct 01, 1988 Electrolysis of metal ions in dilute solutions using vertical planar electrodes results in low recovery. Therefore, an electrolytic cell arranged concentrically with extended cathode surface areas was designed to improve the rate of mass transfer. Three types of gold solutions obtained from industrial sites were used.

  • Gold Refining From Gold Ore to Dor 233 World Gold Council

    Gold Refining From Gold Ore to Dor 233 World Gold Council

    The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple, but it produces gold of only about 99.5 percent purity. The Wohlwill process increases purity to about 99.99 percent by electrolysis.

  • Electrolytic Refining Mining Fundamentals

    Electrolytic Refining Mining Fundamentals

    Electrolysis, or electrolytic refining, is a technique used for extraction, as well as purification, of metals obtained by any refining method. In the electro-refining process, a block of impure metal becomes the anode, and a thin sheet of metal becomes the cathode. Both the cathode and anode are dipped in an electrolytic cell containing an ...

    G10 worksheet for Electrloysis

    3) Extraction of metals from their ores •Metals can be extracted from their ores by electrolysis. Electricity is expensive, so electrolysis is only used to extract very reactive metals such as sodium, calcium and aluminium. •These metals, ‘high up’ in the reactivity series, cannot be extracted by other methods.
