Gekko Systems proudly announced the sale of its 100th InLine Leach Reactor Unit (ILR). The sale marks not only an impressive milestone for intensive cyanidation but also the first sale into Brazil for Gekko. The sale of the ILR to Mineracao Caraiba was signed off by Nigel Grigg, manager of Gekko’s Santiago office, which is still in its first year of operation.
Gekko’s patented ILR is the world’s market leader and the first commercialised intensive leach technology. The technology was initially developed to treat larger volume concentrates from Gekko’s first innovation, the InLine Pressure Jig (IPJ). ‘The ILR is an exciting step-change technology that has seen a rapid uptake by the industry. It has been proven to increase overall plant recovery whilst reducing time-consuming labour practices,’ said Gekko’s technical director and ILR inventor, Sandy Gray.
The first ILR prototype was designed and built in 1997 and, remarkably, is still operating 14 years on at Unity Mining’s Henty gold mine in Tasmania. The prototype provides an insight into continuous evolution and improvements of the ILR design; starting life as a continuous unit treating IPJ concentrates and transforming into a batch unit to treat coarse, high-grade, centrifugal gold concentrates.
The Gekko ILR is a technology and concept that has significantly changed the treatment and recovery of gold in gravity gold circuits and now plays an important role in the treatment of flotation and gravity concentrates. The first five commercial ILR units were sold in Africa to alleviate concerns associated with the security of tabling gold concentrates. Further, the ILR has also had much success and growth in the treatment of silver flotation concentrates in South America. The application of this process allows silver dore to be produced on site.
