Banks has a Dense Media Separation (DMS) process to upgrade the Run of Mine (ROM) material from the underground operations. The DMS plant has an upgraded capacity of 600tpd which rejects about 40% of the feed material allowing high grade sulphides to report to a conventional milling, flotation and dewatering plant. Products exported is Gravity Recoverable Gold and Flotation Concentrate.
The DMS plant mitigates the effects of dilution in the mine and enables a cheaper underground bulk mining method to be used.
