Usually the Solid weight percent of leaching process is 35 to 50% Increasing the Solid weight percent, increase the retention time Furthermore, Increasing the Solid weight percent , reduce the reagents consumption, because the gold recovery can be achieved by a lower volume of solution per tones of ores (Marsden, J, I House, 2006)
The Vat Leaching Process Vat leaching can be described as leaching in a bathtub inside a building Treatment of ore is site-specific as determined by metallurgical tests Bench scale metallurgical testing of ores for their amenability to vat leaching is similar to that for heap leaching First, bottle-roll tests of finely ground material are run,
Other articles where Vat leaching is discussed: gold processing: Cyanidation: ,ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent for several hours in large tanks equipped with agitators For extracting gold from low-grade ores, heap leaching is practiced The huge heaps described above are sprayed with a dilute solution of sodium cyanide .
I also experienced this How much is the acceptable cynide strenght acceptable in a running solution during gold vat leaching On a different note can someone assist me if it is a requirement to add caustic soda in a vat leach process of gold with NaCN
Gold Vat Leaching Technology When it comes to gold extraction, CRONIMET Mining Processing has undertaken a significant amount of work In fact, our team has spearheaded the development of a unique vat leaching process, aimed at improving upon the conventional heap and tank leaching process
In 2011 leaching, both heap leaching and in-situ leaching, produced 34 million metric tons of copper, 22 percent of world production The largest copper heap leach operations are in Chile, Peru, and the southwestern United Stat Although heap leaching is a low cost-process, it ,
“We have acquired the land covering more than 20 acres with the intention of setting up Static VAT Leaching plant producing Raw Gold, at the site we have developed and implemented full-scale operations from fresh ore grinding, separation of free Gold through gravity concentration techniques and thus subjecting the tailings to VAT leaching process to produce Raw Gold
