A review of crystal chemistry application in copper oxide minerals flotation

Crystal chemistry is the theory that study the crystal structure at the atomic level. It is a branch of physics and chemistry that reveals the internal relations between the chemical composition, structure and properties of the crystal and the related principles. The law of constancy of angles, the zone law and the Pauling's rules have laid the foundation of crystal chemistry. Crystal structure and chemical composition are important factors affecting minerals flotation separation, and are also the main research contents of crystal chemistry. Crystal chemistry has been widely used in the copper oxide minerals flotation, including the study on the minerals crystal structure and surface characteristics, such as the mode of occurrence of elements, the type of chemical bond, the polarity of ionic bond, ion radius, solubility and copper ion exposure on the surface of the mineral. The relationship among the copper oxide minerals crystal structure, surface properties and copper oxide minerals floatability and the influence of collector and various adjusting agents on copper oxide minerals flotation and its mechanism analysis are also discussed. Crystal chemistry is one of the important theoretical bases for minerals separation, and plays an important role in minerals flotation. The azurite, cuprite, malachite and chrysocolla are main copper oxide minerals which have industrial utilization values. This paper summarized the research contents of crystal chemistry and its application in copper oxide minerals flotation, introduced the research status of the minerals crystal structure, ionic bond and polarization degree of copper oxide minerals, and the research progress of surface properties and floatability of copper oxide minerals. The application of crystal chemistry in the study of flotation reagent action mechanism and flotation condition control were reviewed, the research directions of crystal chemistry in minerals flotation were pointed out, including that crystal chemistry combined with tests and analysis technologies and a variety of basic theories and disciplines.
