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.

or additional carbon handling cost in leaching, nothing comes for free in mineral processing. Where there is gravity recoverable gold, it is important that it be maximized, as the unit operating cost for a gravity circuit is much lower than that for any other process.
Improved Mining Operations by Detecting Roping and
Aug 17, 2015 Author Douglas Morris One of the most ubiquitous operations in any mine is the use of hydrocyclones (cyclones) in the comminution circuit to sort particle sizes for mineral processing. Downstream of this process is the flotation circuit, which can be adversely affected if there is an upset with cyclones. Poor cyclone performance will impact recovery,
