  • Gold Vat Leaching Technology Xinhai Mining

    Gold Vat Leaching Technology. Once crushing is complete, gold ore is agglomerated and stacked into the vats through the use of conveyors, after which it is left to cure. Following this curing process, the agglomerate is irrigated with cyanide solution at flow rates far higher than those of traditional heap leaching.
