Equipment focus: Scantech Geoscan-M
Real-time mineral analysis has been taken to the next level with the Scantech Geoscan-M analyser shown at the recent International Mining and Resources Conference (IMARC) in Melbourne.
The Aussie-developed Geoscan-M unit is a compact, fully integrated enclosure that is installed over the conveyor to monitor the full flow of ore and concentrates. This removes the need for routine samples to be taken and analysed.
Scantech says the Geoscan-M can provide real-time information, giving updates every two minutes on quality parameters such as impurity levels, moisture content or energy content.
Typical elements the unit can analyse include calcium, silicon, aluminium, copper, zinc, nickel, iron, potassium, titanium, manganese, sulphur, chlorine, magnesium and sodium.
The Geoscan-M uses a radioactive source housed within the heavily shielded enclosure to produce gamma-rays that scan material as it passes.
There is no actual contact with the material as it is scanned. This differs significantly from traditional surface analysis as the beam penetrates through the entire flow of material, giving a much more accurate reading.
The unit then outputs the data in standard industry formats or with Scantech’s own proprietary SuperSCAN format to interface with the plant control system.
Scantech says real-time analysis of material during various stages of production can provide companies with opportunities for plant optimisation and quality control.
The company was founded in Adelaide in 1981 as a small private mineral analysis firm. Today, Scantech is listed on the Australian stock exchange and has over 1,000 units installed in 55 countries (including over 230 in Australia).
