Leaching in Metallurgy and Metal Recovery

Jul 10, 2017· 1) Vat Leaching: Also known as "agitated tank" leaching, the lixiviant comes into contact with the metal material in large vats or tanks, which can be stirred, enhancing the reaction kinetics. The metal containing solid, such as concentrate, ore, residue, or slag, often undergoes size reduction via crushing and grinding prior to leaching.
