Rebellious Ores: Sulfides Selenides and Tellurides

Gold bearing tellurides were important in some of the richest ores at Goldfield Nevada – high grade ore that contained upwards of 10000 ounces of gold per ton. If you have tellurides in your ore it’s important that you are aware of that fact because it affects how you will process it. Tellurides are leachable by cyanide but can take an extended long time period as the telluride minerals have to be dissolved completely by the leaching solutions. There are a several telluride minerals ...

Gold silver platinum and tin are insoluble in this electrolyte and so do not deposit on the hode. They form a valuable ‘sludge’ that collects under the anodes. Soluble impurities of iron and nickel dissolve in the electrolyte which has to be continually purified to prevent excessive deposition onto the hodes which would reduce the purity of the copper.
