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.
Cyanide leaching is a process in which solid natural gold in ore or beneficiation product forms a gold-cyanide complex dissolved in water under the combined action of a leaching agent, an oxidizing agent and a base, that is, a phase transformation process of solid phase gold.
Apr 28, 2021 Clean Mining, part of the Clean Earth Technologies Group, has been working to transform gold production worldwide with a new mineral processing technology that eliminates cyanide in the gold recovery process. This solution replaces toxic cyanide with a non-toxic gold recovery agent, benefiting both human health and the health of the environment.
Apr 12, 2019 Gold is a kind of inactive metal, which can cause complexation reaction with cyanogen CN- under the action of oxygen in the cyanide leaching process, and then results in Au CN 2-. Therefore, cyanide agent dosage is one of the key factors determining the gold dissolution. In general, the pulp should contain a certain amount of unbonded ...
