The purpose of this paper is to discuss the efficient operation of a tailings dewatering circuit comprising a thickener and filter press through proper control and automation._x000D_
It is common to see thickeners and filter press circuits each with their own control systems._x000D_
This can cause multiple issues when trying to increase efficiency and reliability of the tailings management process._x000D_
By automating the thickener and filter press controls, you are eliminating any delays and inconsistencies caused by human error and process variations._x000D_
When done properly the system can maintain a consistent product as the feed characteristics change. Previously, operators would have to monitor the process parameters and adjust the system accordingly._x000D_
This can now be accomplished using state of the art process control equipment that continuously monitors and adjusts critical variables using Programmable Logic Controllers (PLC) and Proportional Integral Derivative (PID) loops._x000D_
The paper will detail the control theory used to maintain these systems, highlight other benefits of having a fully integrated plant such as predictive maintenance and remote diagnostics as well as present examples of how these have been implemented in field examples.CITATION:Baxter, M, Cunningham, R, Williams, R and Zink, D, 2018.
