Detoxification of Cyanide in a Gold Processing Plant ...

2007-11-16  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).

Cyanide Process - Gold Cyanidation Process Gold

2021-11-10  Cyanide Process. Cyanide process is also called as Macarthur-forest Process. It is the process of extracting gold or silver from the ores by dissolving in a dilute solution of potassium cyanide or sodium cyanide. This process was introduced in the year 1887 by the Scottish chemists naming Robert W. Forrest, John S. MacArthur, and William Forrest.

How is Sodium Cyanide Consumed during Gold

2020-8-21  Sodium cyanide is the most commonly used leaching chemical in gold extraction process. According to theoretical calculation, leaching 1 gram of gold only requires 0.5 grams of sodium cyanide. However, in most gold cyanidation plants, the consumption of cyanide is high, which is 50-100 times higher than the theoretical calculation.
