Mac Arthur Process For Leaching Of Silver

Cyanide process metallurgy Britannica

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

Silver Leaching Archives Mineral Processing amp Metallurgy. Introduction to Gold and Silver Leaching. The cyanide leaching process is the most important method ever developed for extracting gold from its ores. The early development of the process is attributed to a Scotchman, John Stewart Mac Arthur, in collaboration with the Forrest brothers.

In cyanide extraction process of silver from argentite ore

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). Leaching is a process used for concentration or benefaction of ore. In
