Impact advanced process control

Process optimisation with measurable benefits 

Impact Advanced Process Control (APC) is designed to improve the stability and performance of mineral processing plants by coordinating how individual control loops and operating objectives work together.

In many plants, grinding, flotation and downstream circuits are controlled in isolation. This often leads to conflicting control actions, unstable operation and conservative operating setpoints. Impact APC addresses this by aligning control strategies across the circuit to support metallurgical objectives such as throughput, recovery and product quality.

Working closely with site metallurgists and operations teams, we design and implement APC strategies that can:

  • stabilise plant operation under changing ore and operating conditions
  • push constraints safely to increase throughput
  • improve recovery consistency
  • reduce unnecessary reagent use and equipment stress

Impact APC integrates with existing PLC and DCS platforms, adding an additional layer of intelligence rather than replacing established control systems. The enabled result is a more predictable, coordinated and optimised plant.

OPERATIONAL GAINS THAT TRANSLATE TO BUSINESS VALUE

By helping reduce process variability and coordinating control actions across the plant, Impact APC enables operations to run closer to their true constraints without sacrificing stability.

In practice, this can deliver:

  • higher and more consistent throughput
  • improved metallurgical performance and recovery stability
  • reduced operating costs through lower reagent consumption and equipment wear.

These operational improvements are designed to translate directly into sustained productivity gains and improved profitability, with benefits that are measurable and repeatable across varying ore types and operating conditions.

 

WORKING AS PART OF YOUR OPERATION TEAM

Our process control engineers work as an extension of your site team, combining metallurgical understanding with control system expertise to address real operational constraints and bottlenecks.

Rather than applying generic control templates, we analyse plant behaviour, identify sources of variability and develop strategies that adapt to changing ore characteristics and operating conditions.

These strategies can be implemented incrementally, allowing efficient testing and validation without disrupting production.

This approach enables rapid learning, practical optimisation and sustained improvements that operators and metallurgists can trust and maintain.

Impact APC can improve grinding circuit stability and throughput by actively managing the interaction between feed rate, mill load, power draw and downstream constraints in real time.

Rather than relying on conservative setpoints and manual intervention, the system responds continuously to changing ore characteristics and operating conditions. This can result in a more stable mill, reduced excursions and the ability to operate closer to true circuit limits.
