The team at Gekko Systems has announced that Ausenco has placed an order for an InLine Leach Reactor (ILR) model ILR100 Batch Automatic unit for installation at Barrick's new Tulawaka project in Tanzania.
The unit will treat gravity gold concentrates from a KC - CD30MS. Earlier in 2003, Barrick trialed a similar model at their Lawlers operation in Western Australia.
Technical Director, Sandy Gray, was delighted to receive the order. " We have been working with the engineers on this project for over eighteen months" he said. Both Gekko's Canadian Office and Australian headquarters have also been liaising with Barrick staff over this time.
"We believe that our technology provides the ultimate kinetic leach environment and is well suited to the recovery of both fine and coarse mineral particles."
The Tulawaka project has a high estimated grade of 11.54 grams per tonne and total cash costs are forecast around US$175 per ounce.
Another InLine Leach Reactor recently installed in Tanzania at AngloGold's Geita Mine and with this sale to Barrick makes the African countries Tanzania and Ghana some of Gekko's highest density installation areas. Equipment is also in operation at Bibiani, two at Obuasi, Geita and Iduaprieum.
"The African continent has led the trend to treat gravity gold concentrates with intensive cyanidation" continued Mr Gray. There are 17 units operating in Africa. However, Australia is catching up quickly with 13 units currently installed or under construction. "The very high recoveries, security and OHS benefits of the technology provides for a strong payback calculation".
