Olubambi et al. studied the effect of pulp density of 5%, 10%, 15%, and 20% (w / v) on the bioleaching of sulphide ores. In the case of Zn, it was found that, the lower the weight of sulfide rock used, the more successful the total metal extraction. For pulp density of 5% (w / v), it was 83.1% and, for 20% (w / v), it was only 45.0%
