Summary: The purpose of investigations proposed by this project is to contribute to a better understanding of the theory and practice of hydrocyclones, especially of such appliances of small diameter. On tools equipped with hydrocyclones of various geometrical parameters o great number of characteristics variables shall be examined using different suspensions. According to the values of individual variables and to results of analytical and graphical interpretation, both their mutual relations and influence on the hydrocyclone will be analyzed. A mathematical model adapted for prognostication of hydrocyclone operations will be constructed. The variable values by which the best working effect can be attained will be determined, be it clasification, thickening or clarification. Suspension samples from different plants will be studied, and optimum hydrocyclone geometry as well as working regime for clear cases will be determined.

Keywords: Mineral processing, Small hydrocyclones, Classification, Modelling, Applications.

Research goals: The aim of the investigations is to study the relations between individual constructive and working parameters on the ground of accessible theoretical insights and experimental work to determine their influence on the phase separation process in the hydrocyclone. It is expected that the proposed investigations shall contribute to the: - better understanding of hydrocyclone theory, - reliable prognostication of hydrocyclone operation by means of mathematical models, - application of small-diameter hydrocyclones in classification, thickening, and clarification.
