How a leading iron ore producer implemented effective real-time decision making for monitoring stockpile composition
BACKGROUND
Effective stockpile management is critical to maximising ore value and maintaining grade specifications in iron ore operations. However, many sites still rely on delayed lab results, often delivered 6–8 hours after stacking, leaving operators with outdated information during critical decision-making windows. A mining operation in Australia faced exactly this issue—manual lab data uploads limited their ability to blend effectively and track high-value ore.
THE CHALLENGE
The mine processed various grades of iron ore daily, but lacked visibility into the real-time composition of material being stacked and reclaimed. This created a risk of inadvertently “giving away” high-grade ore when it was mixed with lower grades or dispatched without recognising its full value. The limitations of delayed lab analysis were directly impacting blending strategy, downstream efficiency, and profitability.
By using the AllScan elemental analyser we could make proactive decisions around how we monitor our stockpiles.
THE SOLUTION
Real Time Instruments (RTI) addressed the issue by installing the AllScan Cf-252 elemental sensor on the stockyard’s conveyor belts. This non-intrusive system continuously monitored the iron (Fe) content of the ore as it was stacked. By integrating the analyser’s live data feed into the existing stockpile management software, RTI created a seamless solution that provided operators with minute-by-minute updates on ore quality, quantity, and location. Operators could now access real-time dashboards showing exactly where high-grade ore had been placed. This visibility empowered the team to plan reclaim strategies more effectively, reduce dilution, and ensure strategic use of premium material.
IMPLEMENTATION & DISCOVERY
RTI collaborated with the mine’s digital and engineering teams to determine optimal installation points and calibrate the AllScan to local ore conditions. During commissioning, real-time readings were benchmarked against lab samples, confirming strong correlation and immediate usability. Once integrated, site personnel quickly adapted to the new data streams. They began using the real-time dashboard to identify grade trends and reclaim high-value ore with precision—transforming what had previously been a reactive process into a proactive, data-driven workflow.
THE RESULTS
The implementation of real-time analysis delivered immediate and measurable benefits:
Real-Time Monitoring: Continuous visibility allowed operators to prevent inadvertent loss of high-grade ore.
Optimised Blending: Strategic blending of premium and regular-grade ore improved consistency and product quality.
Increased Profitability: More than 5% annual profit gain was achieved through improved grade control and efficienc
By implementing RTI’s sensor solution, the operators were able to prevent loss of high-grade ore.
INDUSTRY IMPLICATIONS & FUTURE APPLICATIONS
The success of this solution highlights how real-time elemental analysis can enhance material intelligence and decision-making. Its impact extends beyond iron ore, with opportunities for deployment in:
-
Coal Stockpiles: Managing ash and energy content in real time.
-
Bauxite Yards: Monitoring alumina and silica levels to optimise refining.
-
Port Blending Terminals: Achieving precise grade targets ahead of shipment.
-
Process Plant Feeds: Delivering consistent feedstock for stable operations
CONCLUSION
The integration of AllScan into stockpile management gave the mine a significant competitive edge—combining accurate, immediate data with smarter decision-making. RTI’s solution enabled operators to reclaim and blend more effectively, leading to higher-quality output and better financial outcomes.
