2016-1-1 The introduction of activated carbon to recover gold from cyanide leach solutions in the last quarter of the 20th century had a breakthrough impact on the economics of gold ore processing, as the world gold industry entered a period of unparalleled expansion following the deregulation of the gold price in the mid-1970s.
Application of ion-exchange resins to the recovery of gold is described. Significant developments around gold-selective anion-exchange resins and the commercialization of at least two of these...
Gold cyanide is adsorbed into the pores of activated carbon, resulting in a process solution that is devoid of gold. The loaded carbon is heated by a strong solution of hot caustic and cyanide to reverse the adsorption process and strip the carbon of gold. Gold is then removed from the

Carbon-in-pulp(CIP) solutions were adoptedto process raw gold ore. Raw ore was fed by loader to the raw ore bin underwhich feeder was installed. Ore was fed to the jaw crusher for crushing; thecrushed products were transported by belt to the buffered ore bin, and then fedinto the grinding system.
2018-1-15 In the gold recovery industry, activated carbon from a number of precursors has been used. Due to the nature of the in-pulp process, the following characteristics are important: High affinity towards gold kinetic activity and equilibrium loading. Hard, resistant to abrasion. Density, suited to mixing in pulp.

2021-8-17 Correct me if I am wrong, initially Carbon density is lower than pulp because its pores are not fully loaded with gold and Silver yet, then by the time during the CIL process, the Au and Ag Cyanide will fill the Carbon pores hence the Carbon density will be increased and the possibility to
2015-12-8 The cyanidation process is affected by a number of influential parameters, such as the availability of oxygen at the solid–liquid interface, the pH and Eh of the solid–solvent suspension, the presence of ions other than CN − in solution, the cyanide concentration, the particle size of the mineral, the temperature, the surface area of gold exposed, the purity of the gold
2009-8-26 Gold of either 99.99% or 99.999% purity can be produced from intermediate process products having a wide range of gold contents. The process comprises oxidative leaching of the solid feed, followed by selective solvent extraction of the gold from the leach liquor to reject impurities, and precipitation of high-purity gold powder.

2015-5-1 Plant design parameters for gold extraction, leach residence time and cyanide consumption are generally determined from standard bench-scale bottle roll or agitation leach tests. The application of laboratory data to process design has essentially evolved from the testing of oxide or low cyanide-consuming ores. Such scale-up factors may not be appropriate for ores that deplete cyanide and
