The following conclusions are drawn from this research: (1) the experimental hydrocyclone apparatus designed to allow control of the vortex finder length, overflow diameter, underflow diameter, cone angle, and inlet flow rate, is a suitable system for determining the effect of each variable on the washing efficiency of a conventional hydrocyclone; (2) color-coded spheres of different diameters and specific gravities are suitable to model slurry solids, insofar as size and density is concerned; (3) the concentration of solids used during this work was not a factor and therefore this variable, which is likely to be important in application, was not taken into account; (4) using the experimental hydrocyclone system and spheres along with the concepts of dimensional analysis and similitude, design curves can be generated showing the effect of each parameter on washing efficiency; one hundred eighty-four curves are presented in appendices A-l; and (5) based on the data taken during this project, a particular configuration is recommended for use in recovering coal fines from heavier waste.
