In the AI era: what happens to Mineral Processing Technician
Mineral processing technicians face mixed impacts from AI/automation: tasks like process monitoring and data analysis are enhanced by AI, but manual operations and experience-based decisions have lower automation risk, resulting in moderate job stability.
- CybInteliSense Platform Partial 2021
Replaces some manual tasks of mineral processing technicians in flotation, such as adjusting reagent dosage and aeration based on foam visual features.
- MinOps AI Platform Partial 2022
Replaces technicians in parameter tuning in grinding and classification circuits, such as automatically setting crusher discharge openings and mill speeds.
- AI in Mineral Processing Research Partial 2023
Replaces technicians' manual sampling and assaying of concentrate grades, using models to predict grades in real time and guide process adjustments.
- SmartDozer Tool Partial 2022
Replaces part of the physical and decision-making work of mineral processing technicians in stockpile management and batching, such as automatically planning stacking trajectories.
- Flotation Vision System Product Partial 2020
Replaces the traditional work of technicians observing foam color, size, and texture with the naked eye to adjust reagents, enabling automated visual inspection.
- Real-time monitoring and alarm handling (AI vision systems can automatically identify anomalies)
- Basic data recording and report generation (AI auto-summarizes analysis)
- Simple adjustment of chemical dosage (AI model-based optimization)
- Equipment operation status inspection (replaced by drones and sensors)
- Optimize flotation/leaching parameters using AI models to improve recovery rates
- Using predictive maintenance algorithms to reduce equipment downtime
- Digital twin simulates process scenarios under different ore conditions
- Remote collaboration and AR-assisted maintenance and repair
- Real-Time Prediction of Mineral Grades Based on Machine Learning
- On-site judgment for complex, unforeseen ore changes
- Safety handling and personnel dispatch in emergencies
- Cross-departmental coordination and communication (management, geology, maintenance)
- Hands-on Skills in Equipment Repair and Mechanical Handling
- Basic data analysis with Python or R
- SCADA/PLC system operation and maintenance
- Digital twin and simulation software (e.g., METSIM)
- Statistical process control (SPC) methods
- Predictive maintenance and IoT sensor integration
- Automation Process Optimization (e.g., AI Parameter Tuning)
Entry-level roles are somewhat compressed: automation reduces demand for junior operators, but newcomers need skills in data analysis, sensor maintenance, etc.; entry barriers rise but are not completely closed.
Upgrading from mineral processing technician to 'digital mineral processing engineer': acquiring skills in data analysis, AI modeling, and automated system integration, with future promotion to plant process optimization expert or remote control center supervisor, significantly increasing salary and irreplaceability.

Who it fits
- Background in chemical, metallurgical or mineral processing, targeting Australia's critical minerals processing industry
- Open to FIFO and continuous production environments, seeking high mining sector salaries
- No background in chemicals or process industries
- Not willing to work FIFO rosters or 24-hour continuous production shifts
Career outlook
Process control automation improves efficiency, but process optimisation and troubleshooting still require specialist expertise. A combined background in chemical/metallurgical engineering and minerals is the most competitive combination.
Expansion of lithium battery raw material processing in Australia (Pilbara lithium mines / Kalgoorlie processing plants) and a surge in nickel hydrometallurgy projects have significantly increased demand for technicians with processing and metallurgical backgrounds.
