Hydrocyclone testing

Assess and optimise hydrocyclone performance to maximise your circuit performance

Hydrocyclone Tests can be carried out by JKTech for cyclone characterisation, for benchmarking or to produce JKSimMet model parameters for mineral processing circuit simulation. The tests are conducted at the JKTech pilot plant using hydrocyclones of up to 250 mm in diameter.

The test cyclone is part of a closed system where overflow and underflow are collected in a common sump and recirculated.  Modifications to the standard test equipment can be made.

If simulation of an inclined cyclone is required, it is best to conduct pilot testwork with the test cyclone inclined at the same angle as the proposed cyclone for simulation.  Model parameters can be developed for the inclined cyclone in the same way as for a vertical unit.  Vertical cyclone tests are usually also done on the same material.

Sample requirements: For the smaller range of hydrocyclones, approximately 400 litres of slurry is needed for a suite of tests. According to the range of solid densities requested, this will require between 100 kg and 200 kg of dry material, depending on ore density. The larger hydrocyclones require a minimum of 800 litres of slurry supplied at the maximum possible percent solids. Alternatively, the slurry can be mixed up at JKTech. If necessary, coarse material can be crushed and then ground to a specified feed size by JKTech.
