The cyanidation plants has been using sodium cyanide to dissolve the gold from the ore in order to recover the gold from the leaching solution. The formula is as follows: 2Au+4NaCN+O2+2H2O→2Na [Au (CN)2]+2NaOH+H2O2. 2Au+4NaCN+H2O2→2Na [Au (CN)2]+2NaOH. From the electrochemical reaction, it can be known that dissolving 1 gram of …
Nature of Gold: The surface of a gold particle will typically be dissolved at a rate of around 0.2-0.5 µm of surface depth per hour in a cyanide leach. For large gold particles and nuggets, this is too slow to be fully dissolved in a typical processing plant. Much simpler and less expensive gravity methods are available to recover this gold.

Most cyanide leaching is carried out at a alkaline pH of between 10 and 11, depending upon lab testing of individual ores and the optimum leaching/chemical use rates. The cyanide solution strength is also important in leaching gold, with the typical range of solution being in the 0.02% -0.05% NaCN. The gold particle size has a tremendous effect ...
Cyanide process which is also known as the Macarthur-forest process is widely used in extracting gold or silver from the ores by dissolving them in a dilute solution of potassium cyanide or sodium cyanide. This process was introduced in the year 1887 by Scottish chemists named Robert W. Forrest, John S. MacArthur, and William Forrest.
