Wide-angle hydrocyclone tests were conducted to separate fine (-150 μm) particles based on differences in particle density. Mixtures of ferrosilicon (FeSi) and quartz or lead and soil of similar size ranges were separated in a 25.4 mm diameter hydrocyclone under various test conditions. Separations were made in dense-medium suspensions of fine magnetite and water to improve the overall separation efficiency compared to water-only separations. For the FeSi/quartz mixture, when the suspension relative density was raised to 1.4, FeSi recoveries exceeding 89% with quartz recoveries over 90% were obtained in a single pass through the hydrocyclone. For the lead/soil mixture, lead recoveries exceeding 97% with soil recoveries over 95% were possible at a suspension relative density of 1.3.
