AI-Optimized Comminution Operations

This AI solution uses AI to optimize crushing, grinding, and mineral processing circuits in mining operations, dynamically tuning equipment settings and process parameters in real time. By improving throughput, energy efficiency, and ore recovery while reducing wear, downtime, and manual intervention, it drives significant gains in production output and operating margins.

The Problem

Your comminution circuit leaves millions on the table every year due to static tuning

Organizations face these key challenges:

1

Throughput and recovery swing day-to-day with ore variability, making production forecasts unreliable

2

Control room operators constantly chase setpoints and alarms, but performance still drifts

3

Energy consumption per tonne creeps up over time with no clear root cause

4

Optimization studies show gains in trials, but benefits fade as soon as conditions change

Impact When Solved

Higher, more stable throughput and recoveryLower energy per tonne and reduced wearAutonomous, self-optimizing processing circuits

The Shift

Before AI~85% Manual

Human Does

  • Monitor SCADA/DCS trends and alarms for crushers, SAG/Ball mills, cyclones, flotation, and separation circuits.
  • Manually adjust setpoints (feed rate, mill speed, water/addition rates, crusher CSS, recirculating load) based on experience and shift targets.
  • Run offline optimization projects and test work, then translate results into operating guidelines and SOPs.
  • Diagnose instability (oscillations, surging loads, trips) after the fact and attempt to retune PID loops or change control logic.

Automation

  • Basic PID/PLC control loops enforce fixed setpoints for speed, level, and pressure.
  • Historian/SCADA systems log data and provide trend plots and alarms but do not self‑optimize.
  • Rule‑based interlocks prevent catastrophic failures by tripping equipment when hard limits are exceeded.
With AI~75% Automated

Human Does

  • Define business objectives and constraints (maximize throughput vs. maximize recovery vs. minimize energy) and approve optimization policies.
  • Validate and oversee AI recommendations, focusing on exceptions, constraint changes, and long‑horizon planning (blend strategy, campaign planning).
  • Handle edge cases, safety‑critical overrides, and coordination with mine planning and maintenance (e.g., planned shutdowns, liner changes).

AI Handles

  • Continuously ingest real‑time sensor data (power draw, load, feed size, densities, levels, vibration, reagent flows) and learn the plant’s dynamic behavior.
  • Predict key KPIs (throughput, grind size, energy per tonne, recovery, equipment stress) and compute optimal setpoints subject to safety and equipment constraints.
  • Dynamically adjust crusher gaps, mill speeds, feed rates, water/reagent dosages, and recirculation/partitioning to keep the circuit in its optimal operating window.
  • Detect drifts in ore hardness, fragmentation, or equipment condition and adapt control strategies without manual retuning.

How It Works

AI-Optimized Comminution Operations changes how work is routed, decided, and controlled. This section shows the operating loop, the AI role, and where humans keep authority.

Operating Archetype

Optimize & Orchestrate

AI runs the engine. Humans govern.

AI Role

Operating Engine

Human Role

Governor

Authority Split

AI runs the workflow continuously; humans set policy and intervene on exceptions.

Operating Loop

This is the business workflow being implemented. The four solution levels are different ways to operationalize the same loop.

AIStep 1

Sense

Take in live demand, capacity, and constraint signals.

AIStep 2

Optimize

Continuously compute the best next allocation or action.

AIStep 3

Coordinate

Push those actions into systems, channels, or teams.

HumanStep 4

Govern

Humans set policies, objectives, and overrides.

AIStep 5

Execute

Run the approved operating loop continuously.

FeedbackStep 6

Measure

Measured outcomes feed back into the optimization loop.

Human Authority Boundary

  • The system must not change safety limits, equipment protection limits, or critical operating boundaries without approval from authorized plant leadership.
