Store your gold in the bank, not in your tailings dam

The Carbon Scout technology helps gold mine operators optimise process plant efficiency and reduce soluble gold losses.

The self-contained device collects slurry samples from Carbon In Pulp and Carbon In Leach tanks to determine the distribution of the activated carbon in the pulp for each tank, to an accuracy of ±0.5 grams of carbon per litre of pulp.

The machine improves the accuracy, regularity and consistency of carbon density measurements in carbon-in-leach and carbon-in-pulp circuits.

The Carbon Scout also improves safety by reducing operator exposure to cyanide and other hazards.

Constructed of stainless steel, the ground-based system enhances operator efficiency by removing the need to undertake time consuming manual sampling.

Case Studies & Articles

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.
