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%

The feed pulp density was then varied in the next two experiments, set at 36 wt% solids and then 16 wt% solids, with the density set point at 2000 kg/m 3. All other ...

Washing of iron ore fines and slime (10% and 25% w/v, slurry concentrations) with two types of surface-active agents (sodium humate (synthesized) and AD 200 (commercial)) at varying concentrations at pH 8 was conducted for ascertaining the efficacy ... The settling rate decreases with increasing pulp density. A varialtion in the flocculant dose ...

The present paper reports the flocculation of iron ore slimes from Joda mines of TISeO and Ki riburu mines of SAIL situated in the west Singhbhum district of Bihar, India. These two slimes had marginal difference in ... The effect of pulp density and flocculant dose at neutral pH was studied in the tests. The sedimentation rate increases with ...

The maximum extraction of iron and aluminum was found 589.67mg (80.99%) and 286.45 mg (79.02%) at the pulp density of 5 and 4 g respectively by Acidithiobacillus ferrooxidans.

3.1.2. Effect of Feed Pulp Density. Figure 3 shows that recovery of iron decreased from 93% to 91% for pulp density of 2% to 2.5% at constant magnetic field density of 10,000 mT. Further increase in pulp density caused a relatively decreasing trend in iron recovery and lower silica-alumina gangue removal. The optimum pulp density was obtained at
