Hydrocyclone is widely used in petroleum, mineral and environment engineering, taking advantage of different density material of state of motion under centrifugal force field to deoil, dewater and classify. As a simple, efficient facility, hydrocyclone can be classified as liquid–liquid, liquid–solid, gas–liquid separation types.

Hydrocyclones, used for classification in mineral processing, must be correctly maintained to ensure they operate at peak efficiency. If this essential equipment is not optimised, mineral processing plants will be unable to resolve any operational constraints in their systems. "Supplying only a cyclone is not good enough.
With attempt to solve this problem, a novel Fluidized Hydrocyclone Concentrator (FHC) was designed using hydrocyclone and centrifugal concentration principles for continuous separation of large production of heavy minerals. In this work, the separation performance of the FHC concentrator was investigated with theoretical …
A hydrocyclone can handle very high slurry throughput rates, and often an entire battery of hydrocyclones can be found at a mineral processing facility. The advantage of fast processing by a hydrocyclone is somewhat offset by the associated high impingement …

As a result, the advantages of the improved hydrocyclone over the conventional one have been discovered as follows: ( 1 ) cutting down the short-circuit flow significantly; (2) increasing the energy contributed to the main separation space; ( 3 ) diminishing the internal pressure loss in the hydrocyclone; (4) changing the …
In the mining industry, hydrocyclones are mineral processing equipment used in slurry pulps to separate coarse and fine particles according to their size and density. From Wikipedia: The mixture [slurry pulp] is injected into the hydrocyclone in such a way as to create the vortex and, depending upon the relative densities of the two phases, the ...
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 ...
A friend familiar with this told me the main problem with spiral classifiers is the cut size is directly proportional to retention time (flow rate, Stoke's law, that sort of thing). To get a fine cut size requires flow of almost zero = the finer you want to cut, the lower the flow and density required. Hitzrot, H. W. wrote a great paper in Society for Mining, Metallurgy & …
In the process of crushing and grinding of minerals, some very small minerals will be produced. Minerals with a particle size of 5-10μm are called sludge. ...

At this stage, the mineral is mixed with water and wet milled to an optimal granulometry to achieve flotation. The flotation process yields two products, a concentrate and tail streams, that are sent to dewatering systems for water recovery. These systems usually include thickeners, hydrocyclones, and filters.
