Abstract
This study investigated methods of intensifying the
leaching of zinc oxide ore using sulphuric acid for the improvement
of zinc recovery. The factors that were investigated in this study
were agitation speed, acid concentration and the feeding mechanism
of reactants into the reactor (batch and semi-batch processes).
Analysis of the elemental composition of the ore was performed
using XRF prior to leaching and an Atomic Absorption Spectrometer
(AAS) was used to determine the amount of zinc recovered. The
results obtained, showed that increasing the acid concentration
results in a significant increase zinc recovery...
