摘要

Noranda Inc. Geco Division was a copper-zinc mine that operated for 40 years in Northern Ontario. In 1995, its last year of operation, a new treatment plant was designed and commissioned to treat acid mine drainage (AMD) from the affected area. A new treatment process developed at the Noranda Technology Centre was to offer higher sludge density than existing processes. Modifications made during detailed engineering resulted in a significant difference in the process. Plant start-up posed some important challenges particularly due to sludge pumping problems and an under-sized clarifier. Through a pilot campaign, these problems were resolved. With a different sludge recycle strategy and sand filtration, the plant could not only meet the design guidelines but also surpass them. Over the years, changes in AMD quality and scaling potential made the sand filters unusable. The plant is currently operating well enough to meet today's modified objectives, but significant lessons were learned concerning implication of specialists throughout development of a new process and with the importance of predicting future requirements.
