Cyclone separators | Plant Engineering

By Don Yates January 19, 2016. The use of cyclones as separators would be very popular if unwanted particles in oil and gas applications were consistent in size and would stay away from the walls of the cyclone. Unfortunately, the particles that need to be removed in oil and gas feeds can vary in size, and when they come in contact with the ...

Hydrocyclone

Hydrocyclones demonstrate a trait that is useful for gold mills—minerals with higher specific gravities have a progressively finer cut-size (whether this is desired or not). In plants with free-milling gold, this leads to gold concentrating in the milling circuits (see Figure 17.13).On a size-by-size basis, concentrations of up to 100 times can occur in …
