Calcium cyanide is added at an addition rate of approximately 350 g/t. Due to the large tonnage multiplier, this equates to approxi-mately 1 000 (as 100% NaCN) tons of cyanide

Precious Metal Heap Leach Design and Practice

2020-6-24  Comsur'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.

Factors influencing the rate of gold cyanide leaching and

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

Gold CIL & CIP Gold Leaching Process Explained CCD

2013-1-2  Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach.
