The benefits of accessing real time onstream gold data has been proven with the trial installation of the CSIRO-Gekko OLGA partnership at Evolution’s Mt Carlton operation, converting into a sale and permanent installation.
The unit was installed in December 2018 and trialled on a number of slurry streams including feed and tail before the device was purchased in June 2019. Both CSIRO and Gekko teams worked collaboratively with a very engaged support group from Mt Carlton to deliver a quality outcome.
The alpha system was designed for harsh mine conditions and exhibited high availabilities. Furthermore, sampling accuracy has also been very positive when compared to assay test work on the same sample stream.
In reviewing the data, statistical expert from JK Tech,Prof Tim Napier-Munn made the following comment:
“Based on these data and in this application, OLGA is likely to provide estimates of feed Au concentration that are suitable for use in manual or automatic control of the downstream process, and metallurgical balancing over time” May 2018.
Mt Carlton and the Evolution team have kindly made available some limited sample data. It can be reviewed in our OLGA brochure which can be downloaded by following the button below.
