  • Copper Mining and Processing: Everything you

    The laborious task of mining copper ore by hand made it difficult to obtain large quantities for production. During the Industrial Revolution, coal- and steam-powered machinery paved the way for a huge increase in copper production with mines smelting between 200 and 300 tons of copper ore per week.

    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
