Clean TeQ Holdings’ (ASX:CLQ) proprietary Clean-iX ion exchange...

Clean TeQ Holdings’ (ASX:CLQ) proprietary Clean-iX ion exchange technology has been selected by Carbine Resources (ASX:CRB) as part of its Pre-Feasibility Study for the Mount Morgan gold-copper project in Queensland.

Clean-iX will be used to recover copper, reducing cyanide consumption in the gold circuit, as well as produce a valuable copper by-product, to improve the overall project economics.

The company will work with Carbine and their elected engineers GR Engineering to integrate the process into the flow sheet which reprocesses gold, copper and pyrite tailings at the mine.

During the PFS, the companies will also work together to assess the use of the technology in cyanide recovery and water treatment.

Clean TeQ and Carbine entered into a memorandum of understanding in November 2014 to investigate commercial avenues for the companies to work more closely together for the development of the Mount Morgan project.

Carbine completed a scoping study in November to confirm the technical and economic viability of the proposed flow sheet, which included the use of Clean-iX for copper recovery.

The scoping study confirmed capital costs of A$81.9 million and all-in sustaining costs of US$393 per ounce for a plant processing 1 million tonnes per annum of historical tailings.
