The SART sulfidization, acidification, recycling, and thickening process SP has been successfully implemented in gold cyanidation plants to address issues associated with high cyanide soluble copper content ores However, this process could produce a relatively low grade precipitate, decreasing the sale price when gold plants have high zinc and copper content in their solutions

The integration of the agitation leach plant into the existing heap leach/ADR/SART operation is described Operational problems caused by increasing amounts of copper in the Gedabek gold ores are outlined Previous work on the use of ammonia in copper gold cyanide leach systems is reviewed

Copper precipitates as a salable copper sulphide product in the SART Process and the cyanide that is associated with the copper complex is regenerated as free cyanide After SART, a portion of the SART product solution will be recycled to leach to reuse the free cyanide, while the remaining solution will be used as wash water in the CCD circuit

If the Copper content is from oxide minerals, use the SART Process to lower copper in solution then cyanide as usual You can read more about SART Process in this paper presented at World Gold 2011 in Montreal, October 3 4, 2011: IMPROVING THE ECONOMICS OF GOLD COPPER ORE PROJECTS USING SART TECHNOLOGY

specifically to break apart the copper cyanide complex thereby removing the copper from the gold leach solution and allow effective recycle of cyanide back to the leaching circuit The first step in the SART process is sulphidization where sulphur ions are added to the solution stream This

Copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of 99 99 pure copper called cathodes, which will ultimately be made into products for everyday use

Copper extraction refers to the methods used to obtain copper from its ores The conversion of copper consists of a series of physical and electrochemical processes Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors

In 2011 leaching, both heap leaching and in situ leaching, produced 3 4 million metric tons of copper, 22 percent of world production The largest copper heap leach operations are in Chile, Peru, and the southwestern United States Although heap leaching is a low cost process, it

solution containing the cyanide and copper from the de watering process CCD overflow at Telfer is then fed to the SART plant where the copper cyanide complexes are converted to a copper sulfide precipitate and free cyanide as HCN by the addition of sulfuric acid and sodium hydrogen sulfide NaSH

A single leach test to examine the amenability of the cyanide residue to copper extraction through sulphuric acid was carried out After only 24 hours of leaching, a copper recovery of 34 was obtained In general, the testwork has demonstrated that the SART process is appropriate for this project

Heap leaching Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re separate them after their division from other earth materials

Currently, the SART process has demonstrated to be the best option to treat gold copper ores using cyanide, due to its capability to recover cyanide and produce a saleable copper product

Cyanide Leaching Of Gold Copper is definitely worth mentioning, since copper minerals will dissolve in cyanide solutions, and cause a increased use of cyanide, the copper cyanide complexes formed by the dissolution will tend to inhibit the dissolution of gold in the cyanide solution One is the Merrill Crowe zinc precipitation process
