State the ore dressing process of gold

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

    Apr 30, 2021 Carbon in pulp(CIP)is one of the methods of gold extraction by cyanidation. It is the process of gold cyanide for carbon adsorption after the cyanide leaching of gold-containing materials is completed. In actual production, most CIP plants will encounter various problems, which not only affect the normal operation of gold beneficiation, also seriously damage the economic benefits of CIP
