The method used is the same as was first introduced in 1927 on nitrates, with ore loaded into the vats for batch leaching, then discharged by gantry-mounted clamshells. It is a leach/drain/wash/drain cycle that conceivably could be used with a detoxification cycle in gold leaching and would allow for stackable tailings.

modeling. The objective of this work is to create models of gold leaching in various types of rectors. The results show that batch reactor model fits to experimental data, continuous reactor model allows utilizing it in scheme of series of apparatuses and cascade reactor model makes it possible to evaluate optimal number of reactors in series.
4. Vat-Leaching Process Vat leaching can be described as leaching in a bathtub inside a building. In Vat leaching the ore usually after size reduction (either as a finely crushed or a coarsely ground and de-slimed) is manually loaded into the vats. Vats are tanks built by bricks, cement and sand may be rectangular or circular with a partial filter floor. . Picture 1 and 2
By November 2003, engineering of this plant had commenced, with production at the new ore processing facility in April 2005. Outotec BIOX Process. The Outotec BIOX process was developed for the pre-treatment of refractory ores and concentrates ahead of conventional cyanide leach for gold recovery.

Oct 20, 2014 Nature of Gold The surface of a gold particle will typically be dissolved at a rate of around 0.2-0.5 m of surface depth per hour in a cyanide leach. For large gold particles and nuggets, this is too slow to be fully dissolved in a typical processing plant. Much simpler and less expensive gravity methods are available to recover this gold.
