Some historians claim that the original part of the Donovan Mill, the Dazet Mill, and the adjacent Jackson Cyanide Plant is the location on the Comstock where the cyanide process discovered in Scotland (1887) was revolutionized for processing ore. The use of cyanide and zinc for the retrieval of precious metals was conceived in Scotland in 1887.

Cyanide Leach Process pH Mining: Gold Processing While there are many different processes to remove gold from its encapsulating ore, cyanide leaching (cyanidation) is perhaps the most common and well known. A cyanide solution (NaCN or KCN) is elevated to a high pH level (>) so that free cyanide (CN) will dissolve the gold in the ore.

1. Background. For the past 100 years, the key element in the processing of gold ore has been the cyanidation the years, steady improvements have occurred in equipment design; milling has evolved from stamp mills, through tube mills and ball mills to the large semiautogenous grinding (SAG) and fully autogenous grinding (FAG) circuits in modern gold plants.

Use of Cyanide in the Stamp Battery to treat the ore direct from the stamp milling battery instead of first passing it over amalgamated can be crushed with cyanide solution instead of water, and led at once into the filtering tanks. The results are stated to have shown that the coarse gold resisted the attack of the cyanide for so long a time as to render the process uneconomical.

The presence of base metal ions such as Fe²+, Fe³+, Ni²+, Cu²+, Zn²+, and Mn²+ in the cyanide leach solution will retard the cyanidation of gold. In some cases the naturally occurring carbonaceous materials in sedimentarytype gold ores act as adsorbents for the gold dissolved by cyanide solutions.
