12. Sorption reactions between ionic species and magnetite in aqueous solution
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, leaching, as well as in the formulation of some pharmaceutical preparations. This thesis deals with magnetite and its sorption properties. READ MORE

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

14. Influence of green pellet properties on pelletizing of magnetite iron ore
Abstract : Magnetite iron ore green pellets are produced by balling moist concentrates to green pellets, which are then dried, oxidized to hematite, sintered, cooled and transported to steelmaking plants. The existing theory for balling is based on the capillary theory, but its applicability under industrial balling conditions is unclear. READ MORE

15. Surface reactions of magnetite and maghemite with dissolved and added ions in process water
Abstract : Reactions between mineral surfaces and dissolved species in process water, both inorganic and organic play an important role in mineral processing. Reverse flotation of finely comminuted iron ore is sometimes employed in order to remove the phosphorous mineral apatite. READ MORE
