At Teck-Corona Operating Corporation's David Bell Mine, a successful -water quality management strategy has been established. This resulted from the development and application of process technology, allowing year round discharge of an effluent exceeding the chemical and biological standards set by the Ministry of Environment. This strategy aims at minimizing contaminant levels of effluents through optimization of reagent selection and reduction of effluent volumes through maximizing reclaim water usage. Concentrator and effluent treatment plant operating practices, process chemistry and the results of the water quality management strategy are reviewed.
