1. Spectroscopic studies of colloidal ZnS
Abstract : This thesis is a summary and discussion of four papers, mainly dealing with reactions at the ZnS/water interface. The main analysis method has been spectroscopy. In mineral concentration plants valuable minerals are rendered hydrophobic by the action of certain surface active molecules, so called collectors. READ MORE

2. Ab initio modeling of xanthate adsorption on ZnS surfaces
Abstract : Modeling surface adsorption requires systems of hundreds of atoms. To model such systems at an ab initio level successfully, we need to avoid traditional quantum chemical methods. READ MORE

3. Sulphide mineral collectors adsorbed on a ZnS internal reflection element : an infrared linear dichroism study
Abstract : Separation and concentration of minerals by flotation is a well-known industrial process. In this process collector chemicals are used to modify the mineral surface to increase the hydrophobicity of the mineral particles. READ MORE

4. Orientation of collectors adsorbed at the ZnS/solution interface
Abstract : The separation and concentration of minerals by flotation is a well-known industrial process. In this process collectors are used to increase the hydrophobicity of the surfaces of the minerals. READ MORE
