“…As polymeric dispersants are generally used to disperse titania pigment particles [5], it is very important to understand the interactions between the pigment particles and polymeric dispersants of varying functionality. Extensive research has been performed on the interaction of polymeric dispersants with titania pigment particles [6][7][8][9][10][11]. The type and density of polymer functional groups play a major role in the pigment-polymer adsorption mechanism and stabilisation forces arising from the interfacial behaviour.…”

“…Several authors claimed that dopants reside to a greater degree at the surface as opposed to the bulk [21] while others, in contrast, proposed that the majority of the dopant is held in the bulk of the pigment [33]. A study on the surface and bulk properties of the aluminium-doped titania pigment has shown that aluminium at low concentration was homogenously distributed within the pigment core, with a concurrent high aluminium surface concentration [34].…”

“…Enrichment of minerals by flotation could be effected by interaction of particles the rheological data present an approach to directly understand this interaction. The rheology has been used to investigate particle-particle interactions in slurries of oxide minerals [18][19][20], clays and clay minerals [21][22][23][24], coal [25,26], sulphide minerals [27], and even gangue minerals such as talc [28][29][30]. Accurate measurement of the rheological properties of pulp is rather difficult, because the solid particles tend to settle during measurement.…”

Abstract. The increased exposure to low grade ores highlights the importance of understanding phyllosilicate gangue mineralogy which consists of common gangue minerals. To improve the flotation performance and ore quality the negative effect of the clay minerals on flotation should be identified. The presence of clay minerals leads to problems, such as changing the froth stability, which are related to swelling behaviour, increase in pulp viscosity, overconsumption of reagents, slime coating and mechanical entrainment. The clay content in the ore is changing from time to time and it is necessary to provide quick solutions to the issues caused by the new ore composition. The objective of this paper is to give an overview how to control the colloidal properties of clay minerals on flotation.

To overcome the photochemical activity of rutile used as a pigment and improve its durability in application, hydrous zirconia-coated TiO 2 was prepared by the precipitation method. High-resolution transmission electron microscope (HRTEM) and X-ray photoelectron spectroscopy (XPS) were used to characterize the morphology and surface structure of hydrous zirconia-coated TiO 2 . The ζ-potential and ultraviolet (UV) absorption of both coated and uncoated rutile were examined. The results show that hydrous zirconia can not only improve the durability but also raise the lightness. A suitable ZrO 2 content of hydrous zirconia-coated TiO 2 is about 1.0wt%, and a dense film on the surface of rutile can be formed with better pigmentary properties. Based on the thermodynamic analysis, the zirconia-coating process and the film growth mechanism were discussed.
