Cyanide Process Gold Cyanidation Process | Gold Leaching

Cyanide Process Cyanide process is also called as Macarthurforest 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 Forrest11/06/2009· The equation actually reads as V=ECIt E is the cathode efficiency which is the actual amount of metal deposited by the cathode divided by the theoretical amount given by the first equation The following graph lists some metals along with there efficiency and plating constant It is also possible to determine plating thickness through the equation d = V/A D is the plating thickness in mmEquations used in Electroplating « Electroplating
