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 wear rate of the hydrocyclone internal surface lining by the fast-moving abrasive slurries.
Apr 29, 2019· 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, []
Feb 01, 2012· Hydrocyclone is a key unit operation in mineral processing industries. The principle of operation is based on the concept of terminal settling velocity of a solid particle in a centrifugal field. The conditions in an operating hydrocyclone can be described by reference to Fig. 1. The feed enters tangentially into the cylindrical section of the hydrocyclone and follows a circulating path with a net inward flow of fluid from the outside to the vortex finder
Froth flotation is the use of the physical and chemical properties of the surface of the ore, the use of chemical separation of useful ore. In the process of froth flotation, useful minerals are separated by floating them in the foams, and the way of keeping gangue minerals in the pulp is called positive flotation, while the way of floating gangue minerals in the foam is called reverse flotation.>
The suitable flotation time is determined by mineral processing test. The required flotation time is shorter if the mineral has a good floatability, the content of floated mineral is low, the feeding size is appropriate, the pulp concentration is small, and the reagent action is strong, the air inflation of flotation machine is strong.

« Back. Air-Sparged Hydrocyclone Flotation Technology for Efficient Recovery of Florida Phosphate Minerals. 02-098-156Final. Abstract. The most attractive advantage of air-sparged hydrocyclone (ASH), as a flotation device, is its high throughput (the amount of materials processed per unit volume), which could be up to 200 times greater than that offered by other flotation machines.
Hydrocyclone is necessary equipment for mineral processing in dewatering, classifying and thickening. It plays different role but important role in these processes. For classifying. In gravity processing plant, hydraulic cyclone as classifying equipment processes desliming and classifies fine particles.
Hydrocyclones first appeared in dutch in the late 1800s, Hidrociclon is an equipment that uses rotary current to classify, separate or sort coarse particles of sewage. It widely used in mine processing such as aggregates, hard rock mining, sand, industrial minerals, coal and more. Because the equipment without moving parts, take up small areas, process high volumes and relatively cheap.
A method and apparatus for selectively separating a mixture of hydrophobic and hydrophilic mineral particles. A mineral pulp is prepared which includes minerals ground to a predetermined size. A bubble slurry is then prepared which includes a gas entrained in a liquid to form bubbles of a predetermined size. The mineral pulp and bubble slurry are simultaneously injected into the cell apparatus.
