commenced an R&D program in 2007 to explore the use of their InLine Pressure Jig (IPJ) as a coal separator.
This was in response to the need of several coal companies for a cost-effective method to increase throughput and/or improve recovery in their coal preparation plants.
The research to date has shown that the modified version of the IPJ, aptly named the Gekko IPJ3500 coal separator offers real benefits to the coal washing process.
Leading coal processing consultants, Australian Laboratory Services/ACIRL and Elsa Consulting Group Pty Ltd (ECG) are working with Gekko’s Technical Team on pilot and plant trials.
Andrew Vince of Elsa Consulting Group believes the Gekko IPJ coal separators offer the potential in the coal industry to operate more effectively than teetered bed separators/ spirals/ reflux classifiers due to its controllable jigging action.
The Gekko IPJ coal separators also have the ability to process coarse as well as mid-sized coal, allowing larger diameter dense medium cyclones to be installed by overcoming breakaway size limitations. This could open opportunities for coal preparation plants to reduce magnetite consumption, as well as increase overall plant recoveries.
