The objective of the project is to evaluate the Air-Sparged Hydrocyclone (ASH) and Advanced Froth Flotation (AFF) procedures for their effectiveness in cleaning fine (minus 100 mesh) coal. The two processes will be tested in a circuit capable of processing 0.124 to 0.15 tons per hour of coal at the EPRI-CQDC.

With many of today's oil wells located offshore, the production of high volumes of water compared to oil poses major challenges to oil operators. The use of liquid–liquid hydrocyclone (LLHC) is one effective way to arrest these uphill problems of produced water. However, the nature of fluid flow within the LLHC device is very vital to …

The trends shown in Fig. 16 are confirmed by the solid recovery efficiency and quality of the overflow stream obtained for kaolin separation when operation was carried out at 400 kPa with the hydrocyclone of best performance (D = 50 mm, D o = 10 mm and D u = 9 mm). Thus, the cut diameter drops from 9.5 to 7.3 μm when the standard vortex …

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.
