Abstract

Flotation is the separation of the particles of the
ore according to their relative capacity for floating on a given liquid to
conserve the desired phases. In this study, different size of minerals were
used to achieve better flotation performance. It is devoted to investigate the
influence of particle size on the separation efficiency and to clarify the
availability of the separation mechanism. Prior to this beneficiation process,
surface treatments were applied for obtaining agitated mineral surfaces.
Flotation process provided the separation phenomena between the quartz mineral
and associated impurities. X-ray diffraction (XRD), Scanning Electron
Microscopy (SEM) and Energy Dispersive Spectroscopy (EDS) were used to perform
the phase analysis, surface morphology and elemental analysis of the quartz
ore. It was concluded that the higher amount of flotation product was achieved
with finer mineral. It was explained with the increasing surface area of the
mineral particles.
