The course focuses on the surface chemistry study of multiphase systems involving mineral, liquid, and gas, considering the polarity and surface state of different mineral classes. Theory part include: 1) Surface reactions, intermolecular forces, and interfacial water; 2) Origins of surface charge and electrokinetic phenomena; 3) Surfactants and adsorption reactions; 4) Bubble/drop breakage, coalescence, attachment, and release; 5) Fundamental issues in froth flotation, solvent extraction, carbon adsorption, and semi-conductor fabrication. Hands-on training include: 1) Contact angle and surface charge measurement; 2) Demonstration of spectrometers such as FTIR and SFVS; 3) Molecular Dynamics simulation of a mineral-water interface; 4) Ab-initio simulation.
