Of this, the major portion 60 is consumed at two Ergo dump retreatment plants. Historically the primary motivation for cyanide control at Ergo has been one of leach
The ore is crushed, finely ground and mixed with the cyanide leach solution to form a slurry in an agitation tank. The activated carbon is introduced into the slurry and then removed by screening once it is fully loaded or pregnant with gold. Carbon-in-leach This process is very similar to the CIP process.

The leach circuit comprises eight stainless steel tanks in series, located outdoors. Each tank is equipped with an agitator. The rst tank is a pure leach tank and the following seven are CIL tanks. The otation tailings slurry is pumped to the st tank via a trash screen. Sodium cyanide, slaked lime slurry and air are added into the tanks.
Jul 22, 2019 A typical Witwatersrand gold processing plant comprises two-stage crushing and milling. Milled ore is mixed with water prior to sodium cyanide leaching in aerated tanks. These gold processing plants treat, on average, 150,000 t per month. The plant recovery is usually better than 95 Au Sibanye-Stillwater Limited 2017.

Cyanide leaching has been the industry standard for gold processing for more than 100 years. During the cyanide leach process, a cyanide solution, or lixiviant, is percolated through ore contained in vats, columns or heaps. Gold is dissolved by the cyanide and then removed from the heap or columns.

You can respond to feed variability more quickly and enhance processes - so that your mine ...
Introduction of Vat-Leaching Vat leaching has been around since Roman times, but had become viable in 1896, when cyanide leaching began in earnest with the Merrill-Crowe Process. In an article in the Engineering and Mining Journal in December 1999, Lou Cope described the first vat leaching at Homes take in 1901, which later improved the process ...
The facility, completed in 2002, was the first large grassroots gold mine built in South Africa in 20 years. Avgold wanted the newest technology applied to the plant design, including the broadest possible application of computerized automation. The new gold recovery plant
Dec 01, 1984 Most of the leaching would occur in these two tanks. The remaining leaching tanks in the leaching section would contain carbon, and would act as leaching and adsorption vessels. Because of the large size of these adsorption tanks, the actual concentration of car- bon in the pulp in each adsorption tank

Often, over and above the International Cyanide Management Institute ICMA criteria, local regulatory limitations that are more stringent contribute to the need to lower the cyanide content in gold leach residues. Indications are that the compliance level of 50 ppm CN WAD could be lowered to 20 ppm or less for some geographic areas.

Since oxygen is a key component in the above reaction, it increases gold recovery for a given residence time in the leach tanks. Usually the leach tanks are large and contain only cyanide solution and pulp. The slurry then flows into several CIP carbon in pulp tanks that contain granulated carbon particles.
The ore is crushed, finely ground and mixed with the cyanide leach solution to form a slurry in an agitation tank. The activated carbon is introduced into the slurry and then removed by screening once it is fully loaded or pregnant with gold.
