"WebA cyclone is a device that uses centrifugal forces to classify solid particles, in a liquid stream, by size and/or density. What does a Cyclone do? If a cyclone is fed with a sand and water mixture containing a range of particle sizes, most of the fine sand will report to the overflow (the top of the cyclone), together with most of the water.

How does a dense medium cyclone work

WebOur Cavex® dense-medium cyclone features the innovative laminar spiral inlet geometry design of the original Cavex® hydrocyclone range, but it is cast in strong chrome white iron. This enables the hydrocyclone to outperform in corrosive applications requiring heavy-media separation such as potash, coal, diamonds and hard rock. WebDense media separators are commonly used for preconcentration of coal and diamonds but less commonly for other mineral systems such as lead and zinc. Due to lower head grades adding to the complexities of the ore, multi-stage dense media separators like the Condor can offer some advantages over the single-stage dense medium cyclones.
