  • Gold cyanidation Wikipedia

    Gold cyanidation (also known as the cyanide process or the MacArthurForrest process) is a hydrometallurgical technique for extracting gold from lowgrade ore by converting the gold to a watersoluble coordination complex. It is the most commonly used leaching process for gold extraction.

    Gold Leaching with Copper Minerals present. Bornite is largely soluble under the same conditions, over 90 per cent of it being dissolved in warm cyanide solution in 24 hr. Enargite and tetrahedrite are soluble enough to cause excessive cyanide loss and fouling of solutions with arsenic and antimony.

  • The process design of gold leaching and carboninpulp

    Leaching reagents in the form of cyanide and an oxidant such as air or oxygen are added after thickening. Leaching takes place in a series of agitated leach reactors or pachucas. Before leaching the pH of the pulp is normally adjusted to a value of around 9.511 to ensure minimum loss of cyanide as hydrogen cyanide.

  • The leaching and adsorption behaviour of gold ores

    from the dissociation of the complex is used to leach gold from the ore. The stepwise dissociation of cyanide from coppercyanide complexes can also be used to leach gold from a variety of oxide and sulphide ores. The copper cyanide's fourth ligand readily dissociates at low cyanide concentrations for use in gold leaching.

  • Cyanide Leaching Mining SGS

    Mining Cyanide Leaching. During the cyanide leach process, a cyanide solution, or lixiviant, is percolated through ore contained in vats, columns or heaps. Gold is dissolved by the cyanide and then removed from the heap or columns. It is then extracted from the pregnant leach solution by adsorption on carbon or resins.

    CLS will leach pieces of gold 40 mesh and smaller within 8 to 12 hours. This is a definite advantage over cyanide which can take up to a week to leach 40 mesh gold. This presents a number of tradeoffs between CLS and cyanide. In most cases, the CLS leaching system can be built much smaller than the cyanide system.
