Applicable Minerals


Free gold is unbound to other materials and is easy to liberate.


Gold associated with sulphides requires a modified flowsheet.


Free silver and silver complexes behave unpredictably and contain impurities.

Applicable Processes


A high cyanide and high oxygen reaction boosts recoveries.

Carbon Scout

"Store your gold in the bank and not in the tailings dam"

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


Carbon Scout Benefits


Case Study

We have done a study on why an automated carbon management system is essential for CIL/CIP circuits. Included in the paper is a case study on the benefits of field units operation.

helps gold mine operators optimise process plant efficiency and reduce soluble gold losses

Analyses 10 times more slurry than manual sampling to determine carbon density levels

Accurate and consistent carbon concentration measurements in CIL and CIP circuits while freeing up operators for more critical duties

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 will be responsible for the development, marketing, manufacture, sales and aftermarket support of the Carbon Scout system.

The agreement between Curtin University and Gekko Systems sets the path for further development of the Carbon Scout and process control systems utilising its sampling and data collection abilities.

Unique Solution

• Online detection of Carbon levels
• Analyses 10 times more slurry than manual sampling to determine carbon  density levels
• Single point of measurement for up to 10 CIL/CIP tanks
• Extendable to pH and Dissolved Oxygen measurement
• Integratable to process control systems such as SCADA
• Ground level sampling system for easy collection of GIC samples
• Programmable sampling frequency
• Lease + service package for higher ROI

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.
