The Gekko Difference
Gekko’s specialty is designing complete gravity flowsheet solutions, therefore, Gekko also develop feed preparation processes that bolster gravity concentration recoveries. Combining several Gekko technologies in the same circuit can yield great results when two separate size fractions are targeted.
Removing non-valuable material, using Gekko’s MagScreen, improves grinding capacity and reduces the burden on the gravity concentrator. This long-lasting, low maintenance screen can be easily retrofitted to maximise recoveries. Then Gekko’s Inline Pressure Jig (IPJ) can function optimally to recover gold-bearing particles when contaminating magnetics are not present.
Gravity separation devices, such as the IPJ, are relatively simple. However, the surrounding engineering, including incoming feed preparation, can be complex. Higher recoveries are possible when feed input and feed properties are optimised for the downstream gravity recovery step.
Preliminary testwork is critical to understand an existing circuit’s performance, a unique ore deposit and identify the optimum particle size fraction(s) for the best return. It’s essential that sampling tests be performed by Gekko’s technical services team, before or during the design phase of a feed preparation process, to produce a safe, practical, economical operating circuit. Gekko will provide expert recommendations for developing the most efficient, environmentally responsible feed preparation for gravity circuits.
Feed preparation recommendations can also be sought from Gekko Systems for other grinding circuits such as silver, coal, polymetallics and other minerals. Gekko understand many feed preparation scenarios and offer technical assistance in this area. Contact the Gekko technical services team today.
