Boost metal recovery and process efficiency with advanced process control, condition monitoring and instrumentation to optimize flotation, thickening, milling, and grinding circuits.
Grinding and milling circuits are energy and capital intensive in the entire mining operation. Keeping SAG and Ball mills and high pressure grinding rolls online and running optimally is critical to flotation efficiency and maximizing metal recovery. However, these circuits experience variations in particle size, feed rate and moisture content, which can lead to plugging, high vibration and machine bearing wear, and ultimately unplanned downtime and labor-intensive restarts.
Emerson can help you achieve higher availability in SAG and ball mills and high pressure grinding rolls with advanced condition monitoring solutions to detect issues early. Emerson’s advanced process control solutions can help optimize your grinding and milling circuits and achieve a more consistent grind while reducing energy consumption.

Classification equipment like hydrocyclones and vibrating screens play an important role in the overall performance of the grinding and crushing circuit. Ore misclassification impacts downstream mineral processing leading to increased regrinding, decreased flotation efficiency, higher energy consumption and lower metal recovery. The fundamental problem with operating hydrocyclones and vibrating screens is that they are very sensitive to process changes yet are poorly instrumented. Thus, hydrocyclone monitoring is reliant on visual inspection.
With Emerson’s advanced condition monitoring solutions, you can detect problems like roping and plugging in your hydrocyclones, various emerging problems with your vibrating screens and optimize overall grinding circuit performance.

Optimizing flotation circuits and thickener operations can be complex to achieve due to variability with incoming ore. Performance is dependent on several process variables and minor process disturbance can impact metal recovery and increase reagent use. In addition, flotation and thickener circuits are subject to unplanned downtime due to failure of critical pumps, motors and other associated mechanical equipment.
Emerson’s automation and advanced process control solutions can help you improve process stabilization and optimize flotation and thickener operation. Valve solutions help improve slurry flow management and improve flotation efficiency. Wireless condition monitoring solutions can help minimize unplanned downtime by predicting mechanical failure.

Miners can achieve improved uptime by deploying condition monitoring solutions for SAG/Ball mills and high-pressure grinding rolls.
Miners can increase their throughput and efficiency by applying advanced process control in their grinding circuits.
Integrated quadratic control (IQC) is a newer method of closed-loop control, and its use is growing rapidly for ore processing applications. IQC can be applied in many processes, but has been particularly beneficial in flotation optimization.
Integrated quadratic control (IQC) is a newer method of closed-loop control, and its use is growing rapidly for ore processing applications. IQC can be applied in many processes, but perhaps the greatest sustainability benefit occurs when it is used to improve operation of SAG mills as these typically consume considerable amounts of energy.
