    Elution is the next step in the process, whereby the adsorption of the gold cyanide complex onto carbon is reversed. Loaded carbon is removed from the CIL circuit and the gold stripped from the carbon using a number of treatment steps. The result is a solution of high gold concentration (pregnant eluate).

    In a similar fashion, sodium metal and chlorine gas can be produced by the electrolysis of molten sodium chloride. Electrolytic cells are also used in a process called electroplating.In electroplating, a more-expensive metal is plated (deposited in a thin layer) onto the surface of a cheaper metal by electrolysis.

  • Elution and Carbon Reactivation - Resource book

    In nuclear astrophysics, the rapid neutron-capture process, also known as the r-process, is a set of nuclear reactions that is responsible for the creation of approximately half of the atomic nuclei heavier than iron; the "heavy elements", with the other half produced by the p-process and s-process.The r-process usually synthesizes the most neutron-rich stable isotopes of each heavy element.

  • Process Safety Management for Petroleum Refineries

    Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carbon-in-pulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon.

    The slurry that remains after this process has a very fine particle size. Typically, 80% of the ore particles are less than 70 microns in size (about the same consistency as fine beach sand). Such a fine particle size is required for gold liberation – the size required for the cyanide to be able to 'see' the gold in the leaching process.
