The Gekko Methods workforce has introduced a serious landmark with the sale of its two hundredth manufacturing scale InLine Leach Reactor (ILR) to Marmato Mine in Colombia, operated by Aris Mining Colombia. The InLine Leach Reactor was invented in 1997 by Gekko’s Technical Director and Co-Founder Sandy Grey one yr after the start-up of Gekko in 1996.
The idea of chemically treating gravity gold concentrates quite than utilizing bodily restoration on a shaking desk was pushed by the poor recoveries (50-60%) and low safety related to shaking desk units which had been customary makes use of. Usually, gold crops would expertise a spike in cyclone overflow and excessive tailings grades when gravity concentrates had been being handled by tables within the gold room and earlier than intensive cyanidation grew to become customary in gold operations. Key folks like Nick Mooney and Nick Katsikaros made vital contributions to the idea and efficacy of the operation.
The ILR was the primary commercialised intensive leach expertise and Gekko says it stays the worldwide technical and market chief within the gold trade worldwide. Gekko provides: “Sandy and Gekko’s award-winning technical and design workforce proceed to continuously assessment and enhance ease of operation and recoveries from the unit which generally run round 98-99%. While developed in Australia, the idea actually took off in Africa first with AngloGold Ashanti putting in items in a lot of their operations within the late Nineteen Nineties and is now put in worldwide.”
Totally optimised to mining operations, the ILR boasts constant free gold recoveries of over 98% in addition to superior recoveries of gold from complicated sulphide ores. Leaching coarse (>300 micron) gravity concentrates and recycling leach options delivers low vitality and working prices. Speedy leach kinetics and an automatic system present quick mineral recoveries. Rather than open shaking tables which might be susceptible to theft, the enclosed ILR has lockable entry factors to guard towards theft losses and scale back guide dealing with.
The ILR will be simply retrofitted to any grinding circuit. The modular, small footprint design requires minimal house for integration. The ILR’s chemical dealing with is automated and vital leach parameters are electronically managed, making operations quicker and safer. Tailings generated are smaller and will be coupled with the cleansing of cyanide, which protects the setting.
