Abstract
In this investigation the use of a pulsed perforated plate extraction column is considered for the recovery of sulphuric acid from copper tank house electrolyte bleed using a solvent extraction process based on tris(2-ethylhexyl)amine, TEHA. The hydrodynamic and mass transfer performance of the extraction column is presented and forms the basis for scale up. The results of the pilot plant experiments have demonstrated the viability of operating the acid recovery process using a pulsed perforated plate column.
