  • The Metallurgy of Cyanide Gold Leaching – An

    Leaching gold with a cyanide solution remains the most widely used hydrometallurgical process for the extraction of gold from ores and concentrates. Despite the difficulties and hazards of working with cyanide, no other process has yet been proven to be an economic viable alternative. A paper published by L. Elsner in 1846 first correctly identified the chemical reaction that forms the basis

    The leaching of gold can be conveniently represented by the Elsener equation: [1] Although air agitated leach tanks were commonly used in the industry, mechanically agitated reactors are preferred due to lower operating costs. Typical residence times in the leach section may range from 20–40 hours depending on the head- grade and nature of the ore and the number of leach reactors in series

  • Heap leaching - Wikipedia

    Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the
