AI-Driven Mineral Sorting Systems
AI-Driven Mineral Sorting Systems use computer vision, advanced sensors, and optimization models to identify, classify, and separate ore with high precision throughout the mining value chain. By optimizing mineral phase transformations, beneficiation, and crushing parameters in real time, they increase metal recovery, reduce energy and reagent consumption, and lower operating costs while improving plant throughput and product quality.
The Problem
“Your plant is burning energy and losing metal because it can’t see ore in real time”
Organizations face these key challenges:
Recovery drops whenever ore characteristics change and no one notices until it hits the monthly report
Operators constantly retune crushers, mills, and flotation lines by trial and error
Energy and reagent consumption creep up with no clear root cause or real-time visibility
Product quality and throughput swing shift-to-shift, depending on who is on the control room desk
Lab assays arrive hours or days late, so process changes are always reactive, never proactive
Impact When Solved
The Shift
Human Does
- •Visually assess ore characteristics at key points (mine face, stockpiles, belt) and infer mineralogy and hardness.
- •Set and periodically adjust crusher gaps, mill speeds, and classification/beneficiation setpoints based on experience and delayed assay results.
- •Design and update rule-based control strategies and PID loops, then manually intervene when process conditions drift.
- •Run and interpret lab tests on ore samples (e.g., grindability, mineralogical analysis) and translate results into operating guidelines.
Automation
- •Basic process control (PID loops) maintaining setpoints once humans define them.
- •SCADA/DCS for data collection, alarming, and simple interlocks without intelligent optimization.
- •Batch optimization studies performed offline with simulation tools, not applied continuously in real time.
Human Does
- •Define business and operational objectives (e.g., maximize recovery vs throughput vs energy efficiency) and approve optimization constraints and safety limits.
- •Oversee AI recommendations, handle edge cases, and intervene in abnormal conditions or when models indicate low confidence.
- •Focus metallurgical and process engineering work on strategy, flowsheet design, and high-impact experiments instead of continuous parameter tweaking.
AI Handles
- •Continuously analyze vision, sensor, and process data to identify ore types, mineral phases, and hardness in real time and classify ore streams accordingly.
- •Optimize crusher settings, mill conditions, and beneficiation parameters (e.g., reagent dosing, air flow, residence times) on the fly to maximize recovery and/or throughput within constraints.
- •Control hydrogen-based or other phase-transformation processes by dynamically adjusting temperatures, atmospheres, and times to achieve desired mineralogical changes at minimum energy.
- •Detect shifts in ore characteristics early (e.g., new ore domain) and automatically adjust sorting, blending, and processing strategies to maintain stable performance.

Cloud-Assisted Ore Image Classifier
This level adds a simple camera-based classification layer on top of existing mechanical or sensor-based sorters. Images of ore streams or conveyor belts are periodically captured and sent to a cloud vision service to classify material as ore vs. waste or by broad lithology classes. The system provides decision support dashboards and recommended threshold adjustments, but does not yet close the loop to real-time actuation.

Real-World Use Cases
AI for Mineral Processing and Beneficiation
Think of this as a ‘self-optimizing factory brain’ for mines: it watches every step of crushing, grinding, and separating ore, learns what settings give the best results, and then continuously tweaks the knobs to squeeze out more metal with less waste, energy, and downtime.
Metso AI-Integrated Mineral Processing and Crushing Equipment
This is like putting a very smart autopilot into rock crushers and mineral processing lines. The AI continuously watches how the equipment is running and how the ore behaves, then automatically tweaks settings to get more metal out of the same rock while using less energy and wearing out parts more slowly.
Hydrogen-Based Mineral Phase Transformation Optimization for Polymetallic Oxide Ores
This work is like finding the best recipe and oven settings to bake a cake using less effort and energy. Here, the ‘cake’ is polymetallic oxide ore, and the researchers use hydrogen and controlled heating to rearrange the minerals so that the rock becomes easier to grind and the valuable metals are easier to separate and recover.
Intelligent Mineral Identification and Classification based on Vision Transformer
This is like giving a geologist super-vision glasses: you show it a picture of a rock sample and it tells you what mineral it is, automatically, using a modern image-recognition AI called a Vision Transformer.
