:: BioteQ to Build Demonstration Plant for Sulphate Removal with Freeport McMoRan Copper and Gold

BioteQ Environmental Technologies, Inc., a leader in the treatment of industrial contaminated water, today announced a new development agreement with Freeport McMoRan Copper and Gold to jointly engineer, construct and operate a demonstration plant for the removal of sulphate and other dissolved solids at the Sierrita copper mine site in southern Arizona, using BioteQ’s proprietary Sulf-IXTM ion-exchange technology. The plant, to be constructed in 2008, is anticipated to have a total capacity of 125 gallons per minute. Freeport McMoRan will be responsible for all capital and operating costs; BioteQ will license its technology to Freeport McMoRan and provide the process on an on-going license basis. The demonstration plant will enable Freeport McMoRan to evaluate BioteQ’s technology for potential application at other sites.

Brad Marchant, BioteQ’s President & CEO stated, “We are optimistic about the market opportunities for our sulphate reduction technology, as regulations for sulphate discharge are tightening in many jurisdictions around the world, driving the need for environmental compliance in industries like mining, metal processing, pulp and paper, and chemical manufacturing. We are delighted to be working again with Freeport McMoRan, building on our water treatment project experience together at their Bisbee and Blackwell sites. The Sierrita project will be the first large-scale application of BioteQ’s Sulf-IXTM process."

BioteQ’s Sulf-IXTM technology has several potential advantages compared to other sulphate removal technologies, such as reverse osmosis, including lower capital and operating costs, and elimination of a residual product that would require either further treatment and/or costly disposal. The only by-product of the Sulf-IXTM process is solid gypsum which is commonly used in the manufacture of fertilizers and building products. Gypsum is non-toxic and forms under atmospheric conditions, which is in contrast with conventional membrane processes for sulphate removal that require the energy intensive formation of solid crystals and their subsequent disposal in licensed depositories. It is anticipated that the treated water produced by the Sulf-IXTM process will meet international standards for water recycling for municipal and agricultural applications.
