Gold Leaching with Nuisance Copper with GlyCat process Continuous Vat Leaching CVL The technology has been piloted in North America for both copper and gold ores and a demonstration plant built and operated in Costa Rica in early 2000 CVL vs Heap Leach Case Study Panama
Read MoreMay 27 2017 Crush your ore to the consistency of fine sand in a rod mill then transfer it into a large vat with a strong solution of sodium thiosulfate and agitate it with paddles for a day to a week depending on the size of your vat Finally filter and di
Read MoreVat leach time for gold dissolution approaches that of agitation leaching Vat leaching can be considered when an ore body does not have the grade or quantity to be a candidate for normal agitation leaching and as an alternative to heap leaching
Read MoreA second technique is vat leaching which also requires well leachable ores The required grain sizes of 1 cm are much coarser as compared to agitation leaching because in vat leaching the ore is not agitated in the leaching tanks and only coarse material warrants a good permeability Grain sizes of 2 mm are disadvantageous as they tend to
Read MoreWhen gold dissolution is complete the goldbearing solution is separated from the solids With ores of higher gold content greater than 20 grams of gold per tonne of ore cyanidation is accomplished by vat leaching which involves holding a slurry of ore and solvent in large tanks equipped with agitators
