  • Improvement of Silver Extraction by Ultrafine Grinding Prior

    Ultrafine grinding (UFG) was proposed as a pretreatment method prior to cyanide leaching of old plant tailings of a refractory silver ore. Direct cyanidation of the as-received tailings (d 80: 100 µm) led to a low silver extraction of only 43% over 24 h. A size-based diagnostic study has demonstrated that the refractoriness of the tailings is essentially physical in character.

    The results obtained on leaching of silver with sodium thiosulfate and ammonium thiosulfate showed a low efficiency. The best result was 3%, but without the addition cupric ion or oxidizing agent. In general, it can be concluded that the use of thiosulfate-based solutions for gold and silver extraction of PCB wastes, under the conditions tested, did not show positive results, requiring more studies.

  • The Metallurgy of Cyanide Gold Leaching An Introduction

    Oct 20, 2014 · With lower gold grades beneficiation (usually flotation) is often used ahead of leaching to increase the grade of Au and reduce the quantity of ore to be leached. Nature of Gold: The surface of a gold particle will typically be dissolved at a rate of around 0.2-0.5 µm of surface depth per hour in a cyanide leach. For large gold particles and nuggets, this is too slow to be fully dissolved in a typical processing plant.
