  • Pdf Gold Electrowinning From Cyanide Solution

    The electrolyte in gold electrowinning is the cyanide solution. High throughput of the electrowinning cells provides low cost option for silver produc- ers in particular and therefore leads to increased profit. Electrowinning offers a significantly higher efficiency for gold recovery with low operating cost compared to zinc precipitation methods.

  • Reviewing The Operation Of Gold

    Several reagents are known to leach gold from gold-bearing ores. It has been known for more than a century that alkaline solutions of alkali-metal cyanides e.g. NaCN KCN dissolve gold under aerated conditions. The dissolution of metallic gold is due to the strong
