Real time iron ore quality data provides active process control, with timely information on ore quality to make decisions that maximise the value of the resource and minimise operating costs. This analyser is an economical on-line ore quality monitoring system which is easily installed directly under production conveyor belts. The system does not contain any nucleonic sources and therefore does not require site to obtain a radiation license for its use.
The analyser uses the natural radiation signature of the material and known correlations with the composition to derive ore quality information.
Typical applications include:
• Monitor run-of-mine iron ore prior to stockpiling;
• Monitor run of mine feed to a beneficiation plant;
• Monitor product iron ore.
The IRONSCAN 1500 is used to derive the composition of conveyed iron ores. It can be used as a dilution indicator to monitor quality of mined ore and provide feedback to mining operations. It can also be used to redirect the flow if unsuitable material for treatment is detected. This technology has been found suitable for many hematite and magnetite ores.
"Real-time analysis combines the capabilities of online analysers, mechanical sampling systems, and advanced computer technology to allow buyers, sellers or traders to monitor and correct loading or blending, while these activties are in progress"
