Summary of gold plants and processes.idaho, argentina cyanidation, avrthe future of cyanide in gold processing will also be influenced by the increasing application of cyanide detoxification or recovery processes into flowsheets development of new technologies for the economic recovery and recycle of cyanide from plant tailings.
Highlights worldwide gold recovery on activated carbon grew from zero to almost 70 in twenty years from 1980. the stellar attributes of carbon gold plants led to complacency in the industry in designing and operating these plants. most cip and cil plants are overdesigned and operated sub-optimally. optimum design criteria and operating conditions are easily determined with simple test work.
As silver elutes ahead of gold, it would be expected to have little effect on the design of the elution circuit. however, the data in table 45.2 indicate enhanced silver recoveries at higher elution temperatures for the anglo-american research laboratories aarl elution process. the base data from which this table is constructed were derived at the aarl in johannesburg and are therefore.
In cyanidation, metallic gold is oxidised and dissolved in an alkaline cyanide solution. when gold dissolution is complete, the gold-bearing solution is separated from the solids. with ores of higher gold content greater than 20 grams of gold per tonne of ore, cyanidation is accomplished by vat leaching, which involves holding a slurry of ore.
Individual sub-processes and when combined into an overall batch model were used to show the effect of preg-robbing on gold extraction from ores of different mineralogy. the effect of preg-robbing was found to be closely related to the kinetics of the preg-robbing and adsorption.
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.
Oxidative chloride-, sulfide-, and ammonia-leaching processes are generally more applicable for the extraction of gold or platinum group metals as a byproduct from base metal sulfide.
