At the interfaces between the dispersed phase and the dispersion medium characteristic surface properties such as adsorption and electrical double layer effects are evident and play a very important part in determining the physical properties of the system as a whole. For this reason, surface chemistry is closely linked with colloid science. Colloidal phenomena are very frequently encountered in industrial practice: plastics, rubber, paint, detergents, paper, soil, foodstuffs, fabrics, precipitation, chromatography, ion exchange, flotation and heterogeneous catalysis are just few examples of materials and techniques which deal with matter of colloidal dimensions. The objective of this course is to review the fundamentals of surface chemistry together with the relevant aspects of organic and inorganic chemistry that are important to the control of the froth flotation process. |
