  • Gold extraction Wikipedia

    Generally, recovery of the gold from the sulfide concentrates requires further processing, usually by roasting or wet pressure oxidation. These pyrometallurgical or hydrometallurgical treatments are themselves usually followed by cyanidation and carbon adsorption techniques for

  • Gold cyanidation Wikipedia

    Gold cyanidation 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. Production of reagents for mineral processing to recover gold, copper, zinc and silver represents approximately 13% of cyanide consumption globally, with the remaining 87% of cyanide

  • Electrolytic gold recovery and separation process

    The recovery of gold from its ores is commonly accomplished by one of a number of methods including flotation, amalgamation with mercury or by the cyanide process. Where the gold content of the ore is high, smelting is economical; the cyanide process is employed for the lower concentrations of gold. Where the gold content is very low relative to the amount of other metals contained, these

  • BIOX® Process Outotec

    The process was developed for the pre-treatment of refractory concentrates ahead of conventional cyanide leaching for gold recovery. As the gold is encapsulated in sulfide minerals such as pyrite and arsenopyrite, the gold is prevented from being leached by cyanide. The BIOX process destroys sulfide minerals and exposes the gold for subsequent cyanidation, thereby increasing the achievable

  • What Are Commonly Used Gold Recovery Chemicals?

    Heap leaching gold recovery process is to firstly crush the ore to a certain particle size (-15mm) and then convey it to the storage hopper, adding gold ore, lime and binder according to the specified amount, mixing them thoroughly and sending the gold ore to the disc granulator. After granulation, the gold ore is piled on the non-leakage ground (dip pad). Start pre-soaking with lime solution

  • Gold CIL & CIP Gold Leaching Process Explained CCD

    Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where carbon is added to the leach tanks (or reaction vessel) so that
