Day 51, Procedures to obtain gold: Vat Leaching Process. 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 ...
