The ChemSulphide® plant was built in 2003, replacing a low-density sludge lime treatment plant. BioteQ’s sulphide technology was chosen for the site because it does not produce any metal-laden sludge that would otherwise create an ongoing waste disposal concern in the pristine northern environment. The process operates effectively in the cold northern climate, which allows the treatment season to be extended to 5 or 6 months of the year.
Since the implementation of BioteQ’s ChemSulphide® process, the operating costs for the treatment of the site’s water have been reduced by half. High grade nickel concentrate collected from the process is refined into useful products, contributing a small incremental revenue source that can offset treatment costs, while simultaneously eliminating the production of metal-laden sludge into the environment.
The plant provides reliable operating results. The quality of treated water is consistently proven by bioassay testing of trout and daphnia in undiluted treated water.
The Raglan plant is ISO 14001 certified to meet strict standards for environmental compliance, and all plant operators are fully trained in ISO protocols.
BioteQ’s proven technology and operating expertise ensure reliable and consistent water treatment operations, at a lower cost than an equivalent lime treatment system.
The application of BioteQ’s technology at the Raglan Mine has environmental and economic benefits. The plant:
