In early 2010, Gekko Systems was contracted to design and manufacture a 10 tonne per hour pre-concentration modular gold plant for installation at Morning Star Gold's Woods Point Gold project in Victoria’s eastern goldfields.
The Gekko 10 tonne per hour modular gold plant consists of a two-stage crushing and gravity concentration system, and Managing Director of Morning Star Gold's Woods Point, Nick Garling, is very pleased with Gekko’s involvement.
“Choosing Gekko Systems to supply, install and commission our 10 tonne per hour onsite modular gold plant is a very positive step in Morning Star’s transition from mine developer to producer," says Garling.
The Gekko Systems modular gold plant will process 10 tonne of gold ore per hour by fine crushing to 1mm using a vertical shaft impactor and primary gravity concentration inline pressure jig. The jig concentrate is then further upgraded using an InLine Spinner and Gekko’s regrind mill to produce gold in doré and gold in concentrate.
The innovative combination of fine crushing using the vertical shaft impactor and continuous gravity recovery with the inline pressure jig, results in the liberation and recovery of free and sulphide related gold at its optimum particle size.
Metallurgical test results from Morning Star Gold indicate that the ore’s high free milling gold content will result in 82%-92% recovery by gravity at the target crush size. Importantly, this process flowsheet has resulted in a small plant footprint, and both lower capital and operating costs.
