    The present invention is a process to recover precious metals from sulfide ores. It involves chlorinating a mixture of an ore concentrate and salt to form a liquid melt. The salt preferably contains potassium chloride. This chlorination is carried out at a temperature between 300° and 600° C. while stirring. The process converts precious metals in the elemental and sulfide forms into ...

    13/01/2016 · Well I'll start out by giving you the background on this rock sample. It comes from a section of New Brunswick where Gold and Copper deposits are being loed on a yearly basis. This is an ore from a zone of Copper Porphyry which was loed in southeastern New Brunswick. The overall grade of the ore was assayed at .35% copper and 600ppb AU or gold.

    Cyanide Process

    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 belowThe ore is grounded and crushed.

  • Elution and Carbon Reactivation

    Elution and Carbon Reactivation

    During the CIL process, gold is leached from the ore using an alkaline cyanide solution. The resulting gold cyanide complex ions are then concentrated and separated from the slurry by adsorbing onto activated carbon. Elution is the next step in the process, whereby the adsorption of the gold cyanide complex onto carbon is reversed.
