The aim of this study was to investigate the effect of
conventional supersaturation control strategies on process
efficiency and particle characteristics for copper and zinc
sulphide precipitation reactions under different operational
conditions. The investigation was carried out by first assessing
the effect of biological and synthetic sulphide sources on
metal precipitation at different metal to sulphide molar ratios.
This was followed by the study of metal precipitation in FBR
using synthetic sulphide solutions. The use of multiple
