AUSTRALIAN METS clay content or other characteristics affecting processing performance.”
Combining the elemental results with ReadiMoist TBM moisture measurement and SizeScan particle-size data helps operators distinguish a chemistry change from a physical change in the feed, according to the company. This provides earlier warnings to adjust blending, mill feed rate, crusher settings, reagent / additive dosing and other operating parameters before recovery or throughput is affected.
“ For gold operations, direct measurement of gold in conveyed ore can also provide continuous visibility of feed quality and support ore reconciliation and metal accounting across volumes of material that cannot be represented at the same frequency by conventional sampling alone,” Scantech said.
The emphasis of Scantech’ s more recent projects is moving beyond commissioning the instrument to validating the operational outcome. This is where the ability to match analyser results against independent plant data such as throughput, recovery, energy intensity, reagent consumption, diverted tonnage and final product variability helps. This allows the operation to establish whether an identified change in material quality produced the expected plant response and whether the resulting benefit can be repeated.
“ The value of online analysis is not the number on its own; it is the time the operation gains to act,” Scantech Executive Director and Chief Marketing Officer, Henry Kurth, said.“ If a change is identified before the material is milled, blended or dispatched, the site has an opportunity to protect recovery, cost, capacity and product quality rather than attempt to explain the loss afterwards.”
Scantech’ s technology range now also extends this early-warning approach to equipment protection. SizeScan FOD( foreign object detection) uses computer vision and machine-learning algorithms to identify foreign objects, contaminants and other anomalies in conveyed material, providing real-time alerts, live video, heatmap overlays and a historical record of detected events.
“ When foreign-object detection is combined with particle size, moisture and elemental analysis, an operation can obtain a more complete picture of a disturbance entering the plant,” Scantech said.“ This can provide time to respond to oversize material, unexpected contamination or changing feed conditions before they cause crusher, mill or conveyor damage, unplanned downtime or unstable plant performance.”
The company added:“ The innovation story is no longer just whether an analyser can operate reliably in a demanding
