MillOps 2026: get the base layer right before you reach for AI

At the 2026 Mill Operators Conference, many sites told Mipac their leadership wants advanced process control and AI. Our first question was about their base layer: reliable instrumentation, well-performing PID loops and trustworthy operational data. Without those foundations, APC performance deteriorates, operators lose confidence, and systems get switched off.

APC Readiness in Mineral Processing: What actually stops it from working

APC readiness in mineral processing goes well beyond selecting the right software. Mipac’s Optimisation Team Lead Drew Clements draws on direct site experience to explain why most APC projects underperform – from instrumentation gaps and model drift to operator trust and change management – and what a structured readiness audit actually reveals on the ground.

What is Advanced Process Control in Mining and Mineral Processing?

Advanced Process Control (APC) is a category of automation technology that uses predictive, multivariable algorithms to stabilise and optimise mineral processing circuits in real time. It operates above standard PID control – coordinating multiple interacting variables simultaneously to improve throughput, recovery, energy efficiency and process stability.

The hidden economics of control system design in mineral processing

Control system design is one of the most overlooked economic levers in mineral processing. When done well, it stabilises circuits, reduces downtime and transforms data into meaningful decisions. This article explores the hidden financial impact of strong control foundations and why they matter for leaders, metallurgists and control engineers alike.

Designing tomorrow’s processing plants

Greenfield mining projects shape operational performance for decades. The most successful plants are not defined by equipment alone, but by how they are designed to behave under real variability. Lessons from major projects show that stability, control quality, digital architecture and commissioning readiness must be engineered from day one to create future-ready, optimisation-capable operations.

Fixing control philosophy drift
Brownfield

When control philosophy no longer matches your plant operations

When control philosophy drifts from plant reality, stability drops and APC underperforms. This article explains how drift develops in brownfield operations, the most reliable sequence to rebuild operating truth and why foundations matter more than dashboards for throughput, recovery and reliability.

why your plant is unstable
Brownfield

Why your plant is unstable (and how loop tuning fixes it)

Mineral processing plants often swing between good days and firefighting because of process variability. Poor PID tuning, manual overrides, orebody changes, and instrument drift all erode stability, leading to oscillating mill loads, unstable flotation froth, and volatile KPIs. The fastest, most cost effective way to restore control is targeted loop tuning. By retuning critical circuits and strengthening control strategies, you can turn oscillation into repeatability, improve recovery and grade, and lay the foundation for advanced process control.
