mining cyanide sodium on gold extract

  • Gold cyanidation

    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. Production of reagents for mineral processing to recover gold

  • What is the role of cyanide in mining MiningFacts.org

    What is the role of cyanide in mining? Back to QA List. Cyanide is a naturally occurring chemical that is found in low concentrations throughout nature including in fruits, nuts, plants, and insects. It has been used by the mining industry to separate gold and silver particles from ore for over 120 years. With proper management, cyanide can be

  • Use in Mining International Cyanide Management

    Cyanide is manufactured and distributed for use in the gold and silver mining industries in a variety of physical and chemical forms, including solid briquettes, flake cyanide and liquid cyanide. Sodium cyanide is supplied as either briquettes or liquid, while calcium cyanide is supplied in flake form and also in liquid form.

  • Sodium cyanide

    Sodium gold cyanide. Sodium cyanide is used mainly to extract gold and other precious metals in mining industry. This application exploits the high affinity of gold(I) for cyanide, which induces gold metal to oxidize and dissolve in the presence of air (oxygen) and water, producing the salt sodium gold cyanide (or gold sodium cyanide) and sodium

  • Extraction of gold using cyanide NZQA

    Extraction of gold using cyanide Gold is found in very low concentrations in the ore from which it is mined. To collect the gold from the ore it needs to be separated from the other minerals in the ore. To do this the gold needs to be made into a soluble form so that it can be separated from the other minerals as gold is insoluble. To make gold soluble sodium cyanide
