Wateronly Cyclones in Mineral Processing

An Introduction to Water-only Cyclones. Water-only or Compound-water cyclones (WOC) are commonly used in a fines cleaning circuit, either as a first stage ahead of tables or spirals or as a two stage circuit of their own. The separating efficiency of WOCs has limited their application, but used properly they are easy to set up and operate.
