  • Processing, smelting and refining gold World Gold Council

    Processing, smelting and refining gold. From ore to doré . Cyanidation. More gold is recovered by cyanidation than by any other process. In cyanidation, metallic gold is oxidised and dissolved in an alkaline cyanide solution. When gold dissolution is complete, the gold-bearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of

    Gold Amalgamation Process. In the amalgamation process the ore is run into a “stamp mill” lined with amalgamated copper plates, the mercury on them dissolving part of the free gold. A stream of water flowing through the stamp carries the ore through a screen placed over the discharge gate of the mortar and then over riffles containing mercury where additional gold is dissolved. Sometimes

  • Ore processing Waihi Gold

    Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls. The grinding process reduces the rock to a slurry.
