Abstract. Experiments conducted with a 75-mm-diam hydrocyclone have shown it is possible to obtain an iron ore concentrate containing 60% Fe, 2.65% SiO 2 and 4.0% Al 2 O 3 from Barsua iron-ore washing-plant slimes. About 60% of the iron values are recovered from slimes containing approximately 49% Fe, 8.9% Al 2 O 3 and 11% SiO …

Though the conventional hydrocyclone does not classify ultrafine particles efficiently, the mineral processing industries are still using hydrocyclone to recover the appreciable iron values from Indian iron ore slimes with the desired purity level by the optimised operating and design parameters (Dey et al., 2012).

Introduction: The three-disc magnetic separator is suitable for precisely separating various magnetic mineral mixed ores. It is mainly used to separate fine-grained weakly magnetic materials from non-magnetic materials, such as ilmenite, monazite, tungsten and tin, tantalum-niobium ore, and other dry separation operations. The induction distance …

A. Jankovic, in Iron Ore, 2015. 8.3.3.1 Hydrocyclone separators. The hydrocyclone, also referred to as cyclone, is a classifying device that utilizes centrifugal force to accelerate the settling rate of slurry particles and separate particles according to size, shape, and specific gravity. It is widely used in the minerals industry, with its ...
