:: 10 tph Modular Plant for Morning Star Gold

In early 2010, Gekko Systems was contracted to design and manufacture a 10 ton-per-hour pre-concentration modular gold plant for Morning Star Gold to install at its exciting Woods Point Gold Project, located in Victoria’s historic eastern goldfields and 120 kilometres north east of Melbourne (Australia). This historically rich area is known to have produced six million ounces of gold since the gold rush of the 1850s.

The Gekko 10 tph modular plant consists of a two-stage crushing and gravity concentration system. Managing Director, Nick Garling, is delighted with Gekko’s involvement and commented; “The selection of Gekko Systems in Ballarat to supply, install and commission our 10 tph onsite gravity processing plant is a very positive step in Morning Star’s transition from mine developer to producer. Gekko brings an excellent reputation and a local capability to our operations."

The plant is going to process 10 tph gold ore by fine crushing to 1 mm using a vertical shaft impactor (VSI) and primary gravity concentration InLine Pressure Jig (IPJ). 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 VSI and continuous gravity recovery with the IPJ, results in the liberation and recovery of free and sulphide related gold at its optimum particle size. Metallurgical test results from Morning Star indicate 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.
