The ability to recover cyanide from gold plant tailings has been known almost as long as the cyanidation process has been practiced, but there has been little incentive to process tailings in this way in the past. With. the development of technologies that make it possible to recover and recycle free or complexed cyanide

Because cyanide cannot always leach sulphideassociated gold, regrinding the ore is typically required to expose the free gold for recovery by intensive leaching. Critically, the size at which one can efficiently liberate gold from the host mineral of the particle will determine the process to use for optimal gold .
Carbon in pulp (CIP) is an extraction technique for recovery of gold which has been liberated into a cyanide solution as part of the gold cyanidation process. Get Price Factors influencing the rate of gold cyanide leaching and adsorption ...

Line processing of gold and silver flotation concentrates according to the scheme: gravitational cleaning out the source of flotation concentrate cyanidation leaching and sorption by carboninpulp" followed by desorption of metals with saturated coal, electrolytic deposition from solutions desorption and regeneration of coal, recycling ...
Keywords: Gold, Silver, Mercury, Cyanidation, Knelson concentrator. Introduction Since cyanide used as an appropriate solvent of gold, cyanidation has been a standard process for the recovery of gold and silver [Marsden and House, 2006, Olyaei et al., 2014].
from its ore. The ore is first finely ground and may be concentrated by flotation; if it contains certain impurities, it may be roasted. It is then mixed with a dilute solution of sodium cyanide (or potassium or calcium cyanide) while air is bubbled through it. The gold is oxidized and forms the soluble aurocyanide complex ion, Au(CN) 2 −1 ...

Also, selectivity between chalcopyrite and pyrite in CuAu ores is a challenge ... depression strategies ( aeration, sulphite, cyanide addition, etc.) .
It was concluded that the distribution of oxygen and cyanide along the leach stream determined the extent of gold dissolution. A substantial amount of cyanide (200 – 250 mg/1 NaCN equivalent) was necessary to avoid preferential adsorption of dissolved copper onto carbon in the CIP section.
A flowsheet has been developed to treat the flotation tailings from a copper mine in Mexico to recover gold and silver by cyanidation and carboninpulp (CIP). The plant will treat ~15,000 t/day of a 60:40 blend of current flotation tailings and the mine's historic tailings.
Jun 14, 2014· A client approached hrltesting to investigate options for precious metal recovery from a gold tailings dam project. The project examined options for reprocessing the tailings material in the existing operational site plant. The goals of the project were threefold: Investigate and optimise gold and silver recoveries by cyanide leaching
Recovery of gold in sulfide ores has fallen into several categories. First is froth flotation, and second is cyanidation of the ores. Using cyanide to recover gold from sulfide ores generally results in 30 to 35% recovery, and the best I have heard of is around 50% recovery.
Gravity concentration in rock gold mine is used wide, much as auxiliary process, recovery coarse gold in grinding circuit, create favorable conditions for flotation and cyanidation process, improve the processing performance, improve the total recovery of gold, to increase production and plays a positive role in reducing the cost.
Flotation and subsequent processes (refractory ore processing) The flotation process is described in detail in chapter Native gold, gold tellurides, and sulphides that contain finely disseminated gold can be floated and recovered in a concentrate. In gold metallurgy flotation is often used as a preenrichment process for refractory ores.
