Innovative Technology: Mineralogical analysis
Different methodologies are emerging from the R&D laboratories through automation efforts. I will focus on two:
Automated sample preparation integrated with
X-ray diffraction
using the Rietveld Method
Automatic logging of drill cores using
hyper spectral technology
interfacing to the CSIROs material database.

Performance evaluation
The XRD prep and analysis system was installed to:
Reduce turnaround time (from sample to analysis)
Improve preparation and analytical performance
Cost benefit
Safety improvement
Experiments and analysis have been made to evaluate these targets against the excellent manual laboratory procedures currently in place

Performance target Outcome
Reduce turnaround time
Improve analysis
Cost benefit
Safety improvement

Turnaround time
Method: 8 sample batch from dried coarse sample to XRD analysis. Timed the duration of the process in the manual and automated process
Results:
Manual = 2 hours 29 minutes
Automation = 1 hour 31 minutes
39% reduction in processing time
For the daily capacity of 200 Samples =
56% reduction in processing time

Cross Contamination test in progress
Method: Process sequentially Quartz samples and Copper Ore samples: Q1 Cu1 Q2 Cu2 Cu3 Cu4 Cu5 Q3.
Run this sequence in both the RoboLab and in manual equipment
Results: Robotized system cross contamination = 0.47% distribution of material carryover Manual preparation cross contamination = 0.49% distribution of material carryover

Safety improvements
Many repetitive and hazardous tasks eliminated through the preparation process
Hard to measure, but examples include the dust inhalation, sample lifting, noise, injury from equipment
FLSmidth strives for 4 LTI hours per 1 million hours.

HyLogging advantages Rapid collection of high density spectral reflectance measurements.
• Continuous high-resolution color imagery
• Objective, consistent and effective core logging
• Increased geological knowledge
• Near real time analyses
• Non destructive
• Samples measured in their original trays
• Maximizes the value of drilling expenditure
• Improved geometallurgical understanding
