Blasthole and R/C drill chip sampling and analysis
Today mines have no practical means to estimate ore losses in mining. Accurate 3D model of the bench can be used to measure ore losses. Not only the economic improvements can be reached, but sending sulfidic ore or waste rock to inert waste area can be avoided. Mine planning tools can be used to make economic calculation and chemical analysis shows when waste can be send to inert waste area.
IMA Blasthole Sampler-Analyzers are producing high quality, representative, drill cuttings samples. Both the sampling system and the on-line (XRF) analyzer are now integrated into the drill rig.
The other model, BSA, collects primary samples from the blasthole collar and moves them into the analyzer unit, which then analyzes samples with production speed. Optionally a secondary sampling splitter and bagging device, the Rotary AutoSampler (RAS), Bag & Tag unit can be integrated with the BSA to collect physical samples to the laboratory.
Why IMA Sampler-Analyzers are needed?
Conventional blasthole drill cuttings sampling technology often leads in non-representative ore samples. The reason is that it is impossible to get fully representative samples from cuttings cones formed on the hole collar.
IMA Sampler-Analyzers collect continuously ideal frequent samples (several for every meter). Frequent sampling and instant analysis is superior to any other method available.
