Adjunct Professor Dr Bill Staunton from Curtin University speaks about the operational theory of Carbon Scout
“A ground level, single sampling point, that provides accurate carbon measurements”
A collaboration with Curtin University in 2017 and subsequent installations have demonstrated that our advanced Carbon Scout technology will increase mining site profitability by reducing soluble gold losses.
By advancing the accuracy, regularity and consistency of sampling, the self-contained, ground-level unit will improve measurements in carbon-in-leach and carbon-in-pulp circuits to an accuracy of ±0.5 grams of carbon per litre of pulp.
The Carbon Scout will also greatly improve the safety of your operation by reducing operator exposure to cyanide and other hazards.
“The Carbon Scout is a safe, user friendly and effective means of obtaining regular and accurate carbon measurement data from the CIL circuit.”
– Chris Hitchen, Evolution Mining | Projects and Optimisation Superintendent

How the Carbon Scout works
The process used by the Carbon Scout to determine the distribution of activated carbon produces results in line with manual carbon concentration measurements conducted by plant operators.
The process involves:
> Collecting a sample from the tank
> Screening the sample (to separate the pulp and activated carbon particles)
> Measuring the volume of the activated carbon particles
The accurate sampling capabilities of the Carbon Scout can be utilised for daily laboratory samples as well as future technology enhancements such as online density and mineral analysis.
The Carbon Scout utilizes a unique siphon system to deliver representative samples directly into the unit for analysis. Thus removing operator exposure to Cyanide solution, this machine improves safety, accuracy and consistency of carbon concentration measurements in CIL and CIP circuits.
Combined with SIMCIL process modelling the package will deliver improved carbon management, reduced gold solution loss and free up operators for more critical duties.
