  • redox What is the complete reaction for Cyanide ions

    Silver(I) cyanide react with sodium thiosulfate to produce sodium dithiosulfatoargentate(I) and sodium cyanide. In this case, thiocyanate does not form, rather a complex forms. Explanation of this reaction can be found by observing the related reactions given in the Wikipedia article of sodium thiosulfate.

  • Dissolve Gold and Silver with Cyanide

    The addition of gold or silver to an alkaline sodium cyanide solution will cause the gold and silver to react with the cyanide and dissolve into the solution in a process called cyanidation. This process is more frequently referred to as leaching. As well as reacting with the precious metals, the cyanide will react with iron, copper or zinc

  • Gold cyanidation Wikipedia

    Despite being used in 90% of gold production: gold cyanidation is controversial due to the toxic nature of cyanide. Although aqueous solutions of cyanide degrade rapidly in sunlight, the lesstoxic products, such as cyanates and thiocyanates, may persist for some years.

    And today, over 115 years later, most of the worlds gold is recovered with cyanide playing a large part in the beneficiation of the yellow precious metal. Chemically, it is a rather simple reaction: 4 Au + 8(NaCN) +O2 + 2 H2O = 4 NaAu(CN)2 + 4 NaOH That presumes that the only elements are the gold, Sodium Cyanide and water.
