BioteQ Secures Contract for Testing of Zinc Recovery Using SART

VANCOUVER, BC – BioteQ Environmental Technologies, Inc. (TSX : BQE), a leader in the treatment of industrial wastewater, has secured a  contract with an international gold mining company to carry out test work for a novel application of SART process technology in which cyanide will be regenerated from a zinc-cyanide solution rather than the more usual copper-cyanide solution. The work, which includes laboratory testing and evaluation of the suitability of SART, is expected to be complete by the third quarter of this year. The test work will provide the design criteria for a commercial proposal to supply a SART plant.

Jonathan Wilkinson, BioteQ’s CEO stated, “This project provides an opportunity to test a new application of SART, supporting our customer to reduce operating costs while recovering dissolved zinc from gold processing solution. The contract further confirms BioteQ’s market leadership in innovative SART design and technology solutions. We are hopeful that this test work contract will lead to additional SART work with this new customer and others.”

The SART process (sulphidization-acidification-recycle-thickening) is an enabling technology for copper and zinc-complexed gold deposits. The process, developed by SGS Lakefield and Teck Corporation, can remove the metallurgical interference of cyanide-soluble base metals and regenerate cyanide for recycle to the gold operation. SART can improve gold yields, reduce processing costs, and enhance the environmental performance of gold mining operations.

In the past four years, several new SART plants have been commissioned, and the technology is gaining market acceptance. In an environment of strong gold prices and tightening environmental regulation, gold companies are looking more closely at SART to improve the economics of new, closed or existing mine operations. BioteQ has successfully designed and operated two SART plants, is presently providing SART engineering and commissioning services for Kinross Gold, and is providing early stage test work and design solutions for several international customers.
