What is the optimum method of controlling a cluster of hydrocyclones used in a closed mill circuit so as to obtain the best performance? 


Is simple sump level control sufficient?

Ideal hydrocyclone control is constant pressure, feed density, and flow rate. These three things are difficult to control in the real world which is why people settle for poor hydrocyclone performance by doing sump level control.  Achieving the best combination of pressure, density, and flow requires an advanced control system like MPC or similar.  

One example system (there are many):
