Gold Ore Tank Leaching vs. vat leaching
Tank leaching is typically continuous, while vat leaching is operated in a batch fashion, this is not always the case, and commercial processes using continuous vat leaching have been tested; Typically the retention time required for vat leaching is more than that for tank leaching to achieve the same percentage of recovery of the valuable material being leached;

Vat leaching of gold ores and utilization of the tailings; Kinkoseki no
The Iwato ore is gold and silver bearing silicified porous rock. As most gold and silver in the Iwato ore are concentrated in the pores, leaching of coarse sized ore is expected to be possible. Laboratory tests and pilot plant tests of vat leaching for the Iwato ore were carried out using 0.15-8.0 mm feed.

VAT LEACHING AND ELUTION PLANT
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 in 1906 by adding a desliming circuit.

Agitation Leaching Theory and Practice
Leaching efficiency can be enhanced by the application of Le Chatelier’s principle. In summary, the lower the concentration of gold in solution, the greater the driving force for gold dissolution to occur, although in a mass transport controlled reaction it is debatable what role this plays in gold leaching.
