  • Processing, smelting and refining gold World Gold

    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

  • How to Refine Gold: 2 Major Techniques of Gold

    Aqua Regia gets its royal name from its ability to dissolve some noble metals such as gold and platinum. The diagram below explains the Aqua Regia gold refining process: Figure obtained from Ganoskin www.ganoskin. Since gold naturally occurs as an alloy—in a mixture with other metals—a process such as Aqua Regia will be a good method to obtain gold in its purest form. The physical
