Death Valley NP: Historic Resource Study (Section III)

In 1937 Ed Attaway and Sam Ball, at least, were working the gold mine and trucking their ore to Death Valley Junction for shipment to the smelter. By 1938 ore from the Tucki Mine was being treated by Roy Troeger in the fifty-ton cyanide plant of Keeler Gold Mines, Inc. [ 322] Four months later, in August, Attaway and Ball gave a lease/bond ...

The process design of gold leaching and carbon-in-pulp ...

Before leaching the pH of the pulp is normally adjusted to a value of around 9.5–11 to ensure minimum loss of cyanide as hydrogen cyanide. The leaching of gold can be conveniently represented by the Elsener equation: [1] Although air agitated leach tanks were commonly used in the industry, mechanically agitated reactors are preferred due

Milling is followed by carbon-in-leach or CIL, a 48-h process in which carbon, cyanide, lime, and water are added and the slurry is mechanically mixed and aerated to liberate gold from the ore. Loaded carbon, or carbon with adsorbed gold, is then stripped and electrowinned where gold is desorbed from the carbon deposited on steel wool.

Cyanide Facts | The Cyanide Code

Highly activated carbon is used in the dissolved gold and/or silver recovery process, either by introducing it directly into the CIL (carbon-in-leach) tanks or into separate CIP (carbon-in-pulp) tanks after leaching. The activated carbon adsorbs the dissolved metal from the leach slurry thereby concentrating it onto a smaller mass of solids.

is the extraction of gold from the crushed ore using cyanide and carbon adsorption. This can be done using carbon in pulp (CIP) and carbon in leach (CIL) processes where the gold-cyanide complex binds preferentially to activated carbon. Zinc dust is used as an alternative to carbon at some facilities.

He has described the fundamentals very well, you can also run a varying carbon concentration across your circuit to maximize recovery while minimizing carbon inventory. For example, run 15 g/l in the first two tanks, drop to 5 or thereabouts for the next three, and then increase again for the final two to mop up any gold in solution.
