:: BioteQ Starts Commissioning New Plant in China

BioteQ Environmental Technologies, Inc., a leader in the treatment of metal and sulphate contaminated water, has initiated commissioning of their new plant in China at the Dexing mine site, in joint venture with Jiangxi Copper Company Limited. The $4.2 million plant will recover copper, using BioteQ’s proprietary ChemSulphideTM process, to produce a saleable metal product and clean water that can be discharged to the environment. The project is a 50-50 joint venture with Jiangxi Copper Company Limited, where the project partners share equally in the capital and operating costs, as well as the metals recovered.

Brad Marchant, President and CEO of BioteQ stated, “Our project team is currently onsite to commission the water treatment plant in Dexing, the second of five new construction projects in progress for BioteQ. The Jiangxi Copper Company Limited has been an excellent partner for us in China, providing local knowledge and experienced staff throughout the construction phase. We look forward to working with them to explore additional projects that can use BioteQ’s technology."

The commissioning process, where the plant components are tested and optimized, is expected to take 3 to 4 months. When commissioning is complete, the plant will begin processing metal-laden waste water from several sources at the Dexing mine site, and the joint venture will begin generating revenues. It is anticipated that the plant will initially produce a minimum of 1 million pounds of copper per year. The joint venture plans to increase the volume of water processed in stages. The maximum capacity of the plant is 4.4 million pounds per year, depending on the copper grade and volume of acidic water treated. The high grade copper product will be refined at the Jiangxi Copper refinery at commercially competitive rates.

The Dexing copper mine, located near Dexing City in Jiangxi Province in south-eastern China, currently produces 120,000 tonnes of copper concentrate per year from flotation concentrate and also operates a heap leach using SX-EW to produce copper cathode from low grade stockpiles. Daily production at the mine is 100,000 tonnes of ore and the current resource provides 50 years of operation at current production rates. Mine drainage from waste dumps and low grade stockpiles is acidic and contains copper.
