    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 ore), cyanidation is accomplished by vat

    All base metals, including the lead, are oxidized to form a lead oxide slag. A gold-silver bullion, which also contains any platinum group metals (PGMs) present, remains. If pure gold is required, additional refining steps are necessary to separate out the gold. While this procedure can be used on the very small scale (roughly up to 10 grams) such as in fire assay, its use on a small to medium

  • A Poor Man's Method of Smelting Gold Sciencing

    You can remove the most common metals found in gold ore (copper, zinc and lead) using elements that bond with oxygen at lower temperatures than gold. This oxidation process will make copper oxide, zinc oxide and lead oxide — all of which are less dense than pure gold and will float to the top of your crucible allowing the slag to be sloughed off. Sodium nitrate, silica, and sulphuric acid
