MINERALSCAN 1500 is an economical on-line ore monitoring system which is easily installed directly under production conveyor belts.

Real time 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.

The system does not contain any nucleonic sources and therefore does not require site to obtain a radiation license for its use.

MINERALSCAN 1500 uses the natural gamma radiation (K, U, Th) signature of the material and known correlations with the composition to derive ore quality information, mainly for process control applications.

Typical applications include:

  • Monitor run-of-mine uranium ore prior to stockpiling,
  • Monitor other ores for uranium content, e.g. copper ores (IOCG type, etc),
  • Potash content in ore or product,
  • REE grade in ore where correlation with natural gamma exists (e.g. Th),
  • Divert (bulk ore sort) or blend material based on real time measurements, e.g. used to recover gold in South Africa on a waste conveyor when U3O8 content (associated with the Au) was detected above background in conveyed increments. Sold as GOLDSCAN 1500 and payback on each unit achieved in a few weeks.

""The economic benefit gained from use of the Coalscan on-line ash monitors in most cases results from control of mining and plant operations closer to the required specification ash content. A number of independent studies have estimated the benefits of on-line ash analysis to average more than A$500 000 per year per installed gauge."" March 2011
