Hematite Ore Beneficiation Flow Chart The early hematite beneficiation is mainly gravity separation with machines of jigger, centrifugal separator, spiral chute, spiral washer, shaking table can be involved and later floatation …ABSTRACT The use of a biosurfactant (BS) in mineral flotation offers numerous advantages over conventional surfactants, such as their low toxicity, high degradation kinetics, and potential for selectively treating low-grade ores. In the present study, the use of a biosurfactant obtained from Rhodococcus opacus bacteria for the flotation of hematite from …

Electrophoretic studies of the hematite sample, before BS interaction, found an IEP around a pH of 7.5 and a PZC at pH 7.6. Applying the Guoy-Chapman model and the mixed model of Guoy Chapman and the plate capacitor, it was possible to study the effect of the biosurfactant onto the electrostatic behavior of the hematite particles.Flotation was conducted for ten seconds at a nitrogen flow rate of 20 ml min-i. The effect of pHon the Hallimond cell flotation of natural hematite is shown in Fig. 1. A strong dependence of flotation on pH is evident from this figure.

It is reported that good flotation is obtained in the neutral pH range. The mech-anism of this flotation is not, however, clearly established. Chemisorption of oleate on hematite has been proposed to be the major factor causing the flotation.
