COLORADO – BIOTEQ ENVIRONMENTAL TECHNOLOGIES of Vancouver has received approval the U.S. Environmental Protection Agency to build a plant based on its sulphide technology at the Wellington Oro mine site.
The Wellington Oro mine, located 3 km east of Breckenridge, operated as a zinc-silver mine and has been closed since the 1970s. Surface drainage produces an acidic wastewater that requires treatment before discharge to the French Gulch tributary of the Blue River. The proposed BioteQ plant, with a design capacity of 300 million litres/year, will be designed to recover zinc, lead and cadmium as a zinc-rich concentrate product for shipment off site for final refining. The BioteQ process offers significant benefits for this site as it does not produce any waste metal-laden sludge for long term storage at the site and produces high quality water for discharge directly to the environment.
The current project schedule shows plant commissioning in the fourth quarter 2006. The final construction and operating contract is currently under review. Learn more about BioteQ’s core technology at www.BioteQ.ca.
