The hydrocyclone is an important device used in mineral processing beneficiation circuits for classification of mineral slurries by particle size. One input stream is separated into two output streams; an underflow of coarse particles that undergo additional grinding, and an overflow stream

While in the minerals sands industry, where beaches are often mined for heavy minerals such as zircon and rutile, hydrocyclones are used to separate ultra-fine material before spirals and to dewater the product. The sand containing no valuable material anymore is returned onto the beach.

A new modelling technique for simulating hydrocyclone performance has been developed, in which particles in every size fraction of the feed ore are classified based on ore texture type, taking into account that the same ore texture types in every size fraction of the feed ore have similar mineral contents and densities. Mineral tracking by optical …

Hydrocyclones, supplied by Mozley, with interchange able vortex finders and spigot diameters were used. The size analysis of the feed to the primary hydrocyclones is given in Fig.2. A uniform suspension of slurry was prepared and was kept in circulation in closed circuit for 10 min to achieve steady state.

In mineral processing, the separation of fine mineral particles after the liberation in post grinding circuit is a recognised challenge. One such problem can be noticed in separating fine particles in an iron-ore slimes beneficiation plant (Umadevi et al., 2013). During classification, it is expected that the denser and/or coarser particle ...

"Tantalite's head grade, for instance, is generally between 0,05% and 0,1% mineral in the run-of-mine (ROM) stream, while tin and copper are between 1% and 3% in the initial feed," says Smith. "Compare this to traditional heavy-type minerals such as chrome and iron ore, where the comparison could be 15% to 45%."

In hydrocyclones, dense minerals separate at a finer cut size than lighter minerals. Therefore, liberated magnetite is being concentrated in the cyclone underflow, with consequent overgrinding of the magnetite. Due to this phenomenon the magnetite grinding mills in closed circuits with hydrocyclones are less efficient and have lower capacity ...

HYDROCYCLONES By Richard A. Arterburn For many years, hydrocyclones, commonly referred to as cyclones, have been extensively utilized in the classification of particles in comminution circuits. The practical range of classification for cyclones is 40 microns to 400 microns, with some remote applications as fine as 5 microns or as coarse as 1000 ...
