Optimize high-grade gold recovery with Falcon (1 reply and 1 comment)
Please join and login to participate and leave a comment.
Hello, good day.
I work on a project that we operate with ore with a high gold content. The circuit is composed of gravimetry (Falcon) being fed by the Cycloning Under and the Cycloning Over feeds the flotation and leaching circuit. Currently our global recovery is around 91% and 75 to 80% of this recovery comes from gravimetry (electrodeposition of the intensive leaching solution that leaches the gravimetry concentrate).
We sample feed, concentrate and gravimetry waste, and we assess that the gravimetry waste still has a high gold content. For example gravimetry feed fluctuates between 60-90g/t and waste fluctuates between 40-70g/t.
We currently operate with a 16-minute cycle, Falcon amperage of 28 to 31A, G-Force of 135g and process water flow of 15m3/h. I have the hypothesis that, with this high gold reject, the cycle time could be shorter as there is a possibility of gravimetric gold in the reject.
GRG tests will be carried out in the near future, but gravimetric waste samples were collected to be sent for testing on a benchtop Falcon and considerable recovery was still achieved.
I would like to know if a shorter cycle time can actually increase this global recovery even further? And does the high operating amperage help or hinder the Falcon's operation?
Best regards.
