  • Environment: Cyanide-free gold processing solution

    Currently, around 75% of gold extracted from ore is processed using the hazardous chemicals of cyanide or mercury, which are toxic to humans and the environment. These chemicals are often contained in large storage tanks and, once used, expelled into large tailing dams that can potentially leach into the local surrounds or, worse, burst as we’ve seen in recent years in Brazil and Canada.

  • Cyanide Process Gold Cyanidation Process Gold

    Gold should be separated from other minerals present in the ore. As gold is insoluble, it should be separated from other minerals to make it soluble. Hence, sodium cyanide can be added, where cyanide ions form a complex ion with the molecules of gold. The cyanide process is as explained below-The ore is grounded and crushed.

  • Extracting gold without cyanide Chemical Engineering

    CSIRO gold processing team leader Paul Breuer says the CSIRO process targets small high-grade deposits with good gold liberation at a coarse grind size suitable for the gravity tails to be vat-leached. A tank-leach process using this leach system is under development for demonstration next year.
