Cyanide Leaching | SGS South AfricaCyanide leaching has been the industry standard for gold processing for more than 100 years. During the cyanide leach process, a cyanide solution, or lixiviant, is percolated through ore contained in vats, columns or heaps. Gold is dissolved by the cyanide and then removed from the heap or columns.
ICMI Gold Mining Audit Reportconventional methods of heap leaching with dilute sodium cyanide solution for a 45day leach cycle. The pregnant solution from PLS ponds is processed at the Merrill Crowe and CIC plants. The concentrated solution of the CIC plant (super pregnant solution) is sent to the Merrill Crowe plant for recovery.
CYNOPROBE Online, in Process Cyanide Analysiscyanide includes those cyanide species liberated at a moderate pH of such as HCN(aq) and CN, the majority of Cu, Cd, Ni, Zn, Ag complexes and others with similar low dissociation constants. Mintek has been active in the field of novel instrumentation design, manufacture and installation for industrial plants worldwide since the

When properly characterised, sulphide complex gold ores can be efficiently processed using a Gekko flowsheet design.
Control of pH in the cyanide leaching processIn a milling operation, the plant usually measures pH in the leach tanks. As mill feed varies, so will the pH of the slurry. Adjustments of pH with lime will be made to ensure optimum use of cyanide. Plants now also commonly inject oxygen into the leach tanks to help accelerate the leaching process.
Gold Cyanide Leaching ProcessOutotec's cyanide leaching plants are available as gold adsorption directly from the process slurry in carboninleach (CIL) and carboninpulp (CIP) processes. In addition, dissolved gold can be recovered from the solution after solidliquid separation by MerrillCrowe and carbonincolumn operations.

Precious Metal Heap Leach Design and PracticeComsur's Comco silver heap leach at Potosi, Bolivia, showed the same recovery in both a heap and an agitated leach plant. However, the silver ore leached very slowly and residence time of up to 4 days was needed in an agitated leach plant. Although the heap leach took several months to achieve the same recovery, the economics favored the heap.
Estimating process design gold extraction, leach residence ... · Plant design parameters for gold extraction, leach residence time and cyanide consumption are generally determined from standard benchscale bottle roll or agitation leach tests. The appliion of laboratory data to process design has essentially evolved from the testing of oxide or low cyanideconsuming ores. Such scaleup factors may not be appropriate for ores that deplete cyanide and ...
testing cyanide strenght in gold leaching plant · recover cyanide and maximize operational efficiencies at a gold processing plant in Kazakhstan with high cyanide consumption in the leach circuit. Results from onsite testing demonstrated that up to of copper can be removed and precipitated as copper sulphide and 6090 of cyanide can be recovered from the AVR and recycled for leaching, reducing total overall cyanide use.
