Concentration Tests. If the agitation tests on the sample of ore ground to pass 200 sieve are not satisfactory, it will be necessary to try the effect of concentration. For this purpose take about 500 grams of ore, crushed to No. 30 sieve, and carefully pan twice over. The tailing may then be ground in water or cyanide solution as already ...

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 …

This is done by contacting the carbon with a solution of sodium cyanide. (0.1 to 2% by mass) and sodium hydroxide (0.1 to 2% by mass) at high temperatures (90–120°C). This results in the reversal of the adsorption process with most of the gold desorbing from the carbon back into solution.
