from rapidly draining a head tank. A result of the fluidization process is liquefaction. Liquefaction is similar to the properties of quicksand and results in rapid leaching of the ore. The fluidization process may occur up to 20 times per hour with flows peaking at 30,000 L/h/m2. In comparison, a traditional vat flows at

Vat leach units are rectangular containers (drums, barrels, tanks or vats), usually very big and made of wood or concrete, lined with material resistant to the leaching media. The treated ore is usually coarse. The leaching reagents may be added to the leaching object in different ways.. The vats are usually run sequentially to maximize the contact time between the ore and the reagent.
