We propose a theoretical and experimental approach for optimizing agitated dissolution tanks to minimize energy requirements. Semiempirical equations for estimation of the mass transfer coefficient and the minimum impeller speed for suspension are reported.

view moreThere are numerous types of agitated leaching systems. The common thread is that ore is ground to small particle size (commonly on the order of 10-200 μm) and suspended in a leach solution.
view moreIn the present study, velicity measurements made in a laboratory-scale Pachuca tank have suggested the importance of the fluid flow pattern in governing the performance of air-agitated tanks and have shed some light on the efficient operation of these tanks.
view moreThe acid requirement for the leach is met largely by the acid in raffinate returned to the leach from the copper solvent extraction circuit, through oxidation of elemental sulphur within the leach train, and by acid liberated by the leaching of pyrite.
