BioteQ surpasses treatment target at Raglan, begins commissioning new plant in China
BioteQ Environmental Technologies recently reported that its Raglan operation in northern Quebec has successfully completed its third full season of operations. Between April and mid-November, the facility treated 920,000 cubic metres of water, an increase of 12% over 2006. Process improvements to the original plant design enabled the company to double the processing flow and surpass its budget target of 800,000 cubic metres of water treated.
BioteQ's water treatment plant has since been placed in its scheduled stand-by mode for the duration of the winter. Because Raglan operates in the Arctic, it is a seasonal operation that shuts down when the water source freezes at the site; plant operations are expected to re-start in May 2008 when there is sufficient snowmelt to provide water for processing.
The facility, operated by BioteQ for Xstrata, has replaced a conventional lime water treatment plant and produces no lime sludge requiring storage; at the same time, it has recovered 12,500 kilograms of nickel in concentrate for reprocessing by Xstrata. BioteQ further reports that the plant has continued to meet all regulations for water discharged to the environment, achieving <0.2 parts per million nickel concentration, less than half the regulatory standard.
In other recent developments, Vancouver-based BioteQ has begun commissioning a new $4.2-million facility at the Dexing mine site, near Dexing City in the southeastern China province of Jiangxi. The project, a joint venture with Jiangxi Copper, will use BioteQ's proprietary ChemSulphide(tm) process to produce a marketable metal product and effluent clean enough to be discharged safely to the environment.
The commissioning process, in which the plant components will be tested and optimized, is expected to take three to four months. Once this phase is complete, the plant will begin processing metal-laden wastewater from several sources at the Dexing mine site, producing an anticipated minimum of one million pounds of copper per year.
BioteQ's commercially proven technology treats acid mine drainage and other metal-laden waste water by sequentially removing metals and sulfate. More information is available on the company's Web site, www.bioteq.ca.
Jiangxi is China's largest copper company and also produces sulfur, gold and silver. The state-supported company operates five large copper mines in China, including Dexing, the largest open-pit mine in the country.Table of Contents
