2. 1. Interaction of magnetite with soluble silicates and bentonite : implications for wet agglomeration of magnetite concentrate

   Author : Xiaofang Yang; James McQuillan; Luleå tekniska universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical Chemistry; Fysikalisk kemi; Chemistry of Interfaces; Gränsytors kemi;

   Abstract : Iron ore green pellets are produced by agglomeration of moist magnetite concentrates. The quality of green pellets is essential for the transportability and metallurgical benefits of the final product. READ MORE

4. 2. Scanning probe microscopy studies of interaction forces between particles: emphasis on magnetite, bentonite and silica

   Author : Illia Dobryden; Neil Thomson; Luleå tekniska universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Experimentell fysik; Experimental Physics;

   Abstract : Scanning probe microscopy (SPM), such as the atomic force microscope (AFM), using colloidal probes is a highly suitable technique to probe single particle-particle interactions in aqueous solution. The interaction force between a colloidal probe on the AFM cantilever and sample surface is measured. READ MORE

5. 3. Adsorption and surface reaction properties of synthesized magnetite nano-particles

   Author : Payman Roonasi; Luleå tekniska universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

   Abstract : The surface chemistry of inorganic materials is of great significance in a number of industrially important processes such as separation of ore by flotation, catalysis, water purification, paper coating and pharmaceutical industry. The purpose of this study has been firsly to develop a method for optimal synthesis of magnetite nanoparticles and secondly to utilize these particles as adsorbent in order to investigate their adsorption/desorption properties.
