Metris Scrubber ACE applies advanced process control to scrubbing circuits used in mineral processing for surface contaminant removal and particle liberation. The solution optimizes scrubber speed, residence time, water addition, and feed rate simultaneously, improving downstream separation efficiency and product quality in phosphate, silica, and industrial minerals operations.
Attrition scrubbing is used in minerals processing to remove clay coatings, surface contaminants, and weak intergrowths from valuable mineral particles, improving downstream separation efficiency in flotation, magnetic separation, and gravity circuits. Consistent scrubbing performance depends on maintaining optimal scrubber speed, slurry density, residence time, and water addition—variables that interact and whose optimal settings vary with ore mineralogy and feed grade.
Metris Scrubber ACE uses model-based predictive control (MPC) to manage these interactions in real time. The controller continuously adjusts scrubber operating parameters to maintain target scrubbing intensity and residence time while preventing overloading or underperformance across varying feed conditions.
The solution integrates with existing DCS infrastructure and the Metris All-in-one platform, providing real-time visibility of scrubbing circuit performance and downstream beneficiation KPIs. Scrubber ACE can operate stand-alone or as part of a broader Metris Operational Performance Package (OPP).
