- Online detection of carbon levels
- Automated carbon management system
- Single point of measurement for multiple CIL/CIP tanks
- pH and Dissolved Oxygen measurements
- XRF to measure gold on Carbon for real time gold circuit inventory.
- Save 3+ hours per day through automatic sampling
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

The technical team at Gekko Systems is pleased to release further data supporting the benefits of new technology that optimises carbon management systems in gold processing facilities. Optimising carbon management in the CIL circuit reduces gold solution losses and...
XRF addition to Gekko Carbon Scout design enables gold in circuit to be automatically calculated
Gekko's Carbon Scout was installed at the Stawell Gold Mine in Victoria, Australia, in 2019 with the aim of optimising carbon transfers. The unit was recently upgraded in 2021 with a new X-ray fluorescence (XRF) technology to allow the operation to calculate...
The Carbon Scout was developed by Dr Teresa McGrath and Adjunct Professor Bill Staunton from Curtin University, in association with Bill McCallum from Havilah Consulting.
Gekko Systems has licensed the technology from Curtin and is responsible for manufacturing, sales and aftermarket support of the Carbon Scout.

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.
