Rabbit Lake Uranium Mill Complex, Canada

As the ore grade declined, it became necessary to treat 2,000 tons per day rather than the designed 1,500. To achieve this increased tonnage, Fluor subsequently installed a ball mill following the cascade mill. The ball mill operates in a closed circuit with the hydrocyclones. The diesel generator plant consisted of three 2,500-kilowatt units.
