In metallurgical processes tank leaching is a hydrometallurgical method of extracting valuable Leaching reagents are added to the tanks to achieve the leaching reaction. Agitation is further assisted by the use of tank baffles to increase the efficiency of agitation and prevent centrifuging of slurries in circular tanks.
