A stamp mill consists of a set of heavy steel ( iron shod wood in some cases) stamps, loosely held vertically in a frame, in which the stamps can slide up and down. They are lifted by cams on a horizontal rotating shaft. As the cam moves from under the stamp, the stamp falls onto the ore below, crushing the rock, and the lifting process is ...

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.

Except for the stamp mill. And what a really neat little stamp mill it is. There is a row of four Nissen stamps with automatic ore feeders behind each one. Each stamp has its own individual mortar box to crush the gold ore. The crushed ore would have washed out onto a missing amalgamation table and then it looks like into some cyanide tanks.

Stamps drop at a rate of about 100 per minute and grind about 3 to 5 tons of rock per stamp per 24 hr. Water consumption averages around tons per ton of ore. The stamp mill was originally devised as a combination grinding and amalgamating device before the days of cyanidation.

Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carboninleach. This is a gold extraction process called cyanidation where carbon is added to ...

Currently the processing plant is equipped with a 3 stamp mill to process run off mine ore. The mill is coupled to a Jamestable for amalgamation of free gold using mercury. Sands from the stamp mills are being stock pilled for further processing using cyanidation once the carbon in leach circuit is complete. Current gold production is 5000g/month.

The cyanidemill was erected at so great a distance from the stampmill that a separate crew of workers and a separate powerplant were necessary. No arrangement had been made for the treatment of the concentrates as produced; although later, an adobe roastingfurnace had been erected near the stampmill, as well as a small cyanideplant, for ...

The process can take 2460 h of cyanidation, depending on the intensity of agitation and aeration of the tanks. Once the gold is dissolved in the cyanide solution, two techniques are commonly used to recover it: (1) adsorption of gold onto activated charcoal, or (2) gold precipitation with zinc. Fig. 2.

In the leaching circuit, the ore slurry, commonly referred to as "pulp", is then subjected to leaching in a series of sequential agitated cyanidation tanks, to which cyanide is added and air is sparged into, to enable gold leaching (Adams, 1989). Once solubilized, gold adsorption occurs in a separate series of agitated tanks, in the case of ...
