  • (PDF) Cyanidation kinetics of silver telluride...

    For this purpose, cyanidation experiments were carried out to: (1) study the difference between the cyanidation kinetics of elemental silver and silver telluride; (2) study the effect of temperature (i.e. 20, 25, 27, 30, 35 and 40°C) on silver telluride dissolution; and (3) elucidate the kinetic mechanism of the silver telluride cyanidation.

    of cyanide, a process that has great potential but has not been tested in a commercial setting. Environmental Concerns . Both the use and disposal of cyanide present significant safety and environmental risks. Cyanide and cyanide gas are both extremely toxic and great care has to be taken during ore processing to avoid exposure for workers.

  • EXTRACTION OF GOLD AND SILVER BY CYANIDATION PROCESS

    In the second part the cyanidation process was applied on roasted and un-roasted ore samples. The cyanidation time and grinding time were optimized. The maximum grade of gold 71.82 ppm and silver 25.95 ppm was extracted from roasted ore samples at cyanidation time of 35 hours and grinding time of 30 minutes as compared to

  • Gold cyanidation Wikipedia

    Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex. It is the most commonly used leaching process for gold extraction.
