Gekko branches out

GEKKO Systems has signed a deal to commercialise Curtin University-developed Carbon Scout carbon concentration measurement technology.

The deal marks a major departure on two fronts from Gekko’s normal operating method. Over its 20 year history the company has specialised in developing its own processing technology. Also, over those two decades it has deliberately stayed clear of the carbon-in-pulp and carbon-in-leach gold processing technology sphere.

Carbon Scout was developed by Dr Teresa McGrath and adjunct professor Bill Staunton from Curtin University in association with Bill McCallum from Havilah Consulting.

It is designed to replace traditional manual techniques used in gold extraction with automated measuring technology.

The technology is aimed at improving the accuracy and consistency of carbon concentration measurements in carbon-in-leach and carbon-in-pulp circuits.
 It also improves safety by removing operator exposure to cyanide and other hazards.

Gekko has licenced the technology from Curtin and will be responsible for marketing, manufacturing and selling Carbon Scout.

The agreement between Curtin and Gekko sets the path for further development of Carbon Scout and process control systems using Carbon Scout’s sampling and data collection abilities.

The technology is being trialled at mine sites operated by AngloGold Ashanti.

AngloGold Ashanti project metallurgist Chris Ypelaan said initial indications during the development of Carbon Scout had been promising.

He said it was showing signs of meeting the needs of accurately and consistently measuring carbon concentrations in the mine’s CIL circuit.

“Better carbon management through automation of carbon forwarding pumps will help to minimise gold solution losses and will require less input from operators, allowing them to better use their time in other areas,” Ypelaan said.

Gekko Systems technical director Sandy Gray said the development of Carbon Scout not only increased process plant efficiency but also safety and operations stability through intelligent control systems.

“The technology enables optimal gold recovery thus improving overall profits,” he said.

“The Carbon Scout will undertake further quality control testing and optimising at beta test sites with a full launch proposed in the first half of 2017.”
