    • Cyanide Process Gold Cyanidation Process Gold Leaching

      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.
