Detoxification of Cyanide in a Gold Processing Plant ...

Cyanide is present in the effluent waters of several industries. The mining and mineral processing industries, especially gold processing, use a great amount of cyanide (Ingles and Scott 1993), as do a number of chemical synthesis (nylon, fibers, resins, herbicides) and metallurgical (plating and surface finishing) processes (Mosher and Figueroa 1996; Patil and Paknikar 2000).

Factors influencing the rate of gold cyanide leaching and ...

But operating the plant at higher gold loadings slows the rate of adsorption of gold cyanide onto carbon and increases the gold losses in the barrens solution. This can be seen by comparing the profiles in Runs 2, 8 and 9, where the up-grading ratio was varied from 610 to 1000 to 1420, resulting in an increase in soluble gold losses from 0.001 ...
