Pressurised tank leaching is one of several [[leaching methods]]. Chemical dissolution of soluble minerals within a solid ore or concentrate carried out at elevated pressures and giving rise to a solution containing metals to be recovered. The increased pressure used in the pressure leaching process improves the solubility rate of solids and increases the speed of dissolution into the leach solution. Pressure leaching is carried out in closed autoclaves which permit higher temperatures than are possible with open tanks, this also increases the dissolution rate.

Pressurised tank leaching is one of several leaching methods. Chemical dissolution of soluble minerals within a solid ore or concentrate carried out at elevated pressures and giving rise to a solution containing metals to be recovered. The increased pressure used in the pressure leaching process improves the solubility rate of solids and increases the speed of dissolution into the leach solution. Pressure leaching is carried out in closed autoclaves which permit higher temperatures than are possible with open tanks, this also increases the dissolution rate.
