Extraction Of Silver By 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.

Extraction of Silver by cyanide process and its uses. Silver also occurs both in combined state as well as in free state. The important ores of silver are: Argentite (Ag 2 S), Copper silver glance, Horn silver, Ruby silver. The silver ores are found along with gold ores in some parts of India.

Cyanide process, also called Macarthur-forrest Process, method of extracting silver and gold from their ores by dissolving them in a dilute solution of sodium cyanide or potassium cyanide. The process was invented in 1887 by the Scottish chemists John S. MacArthur, Robert W. Forrest, and William Forrest. The method includes three steps: contacting the finely ground ore with the cyanide ...

The extraction of silver involves in cyanide process are:(i) Ag2S + 2CN- + O2 → 2[Ag(CN)2]- + SO2(ii) [Ag(CN)2]- + Zn → [Zn(CN)4]2- + AgThus, in equation (i) O2 act as oxidising agent (Oxidise sulphide to SO2) and in (ii) Zn act as reducing agent (reduce Ag+ to Ag).
