Henderson expands: Implements new process automation system

The Henderson Mill, Climax Molybdenum Co, a subsidiary of Phelps Dodge Corp, is located approx50 miles west of Denver, Colorado, USA, and is the largest primary producer of molybdenum disulfide in the world. Spanning both sides of the continental divide, the mill processes the mineral deposit, generating a molybdenite concentrate for shipment to other company facilities for processing in numerous steel and chemical industry applications. To optimize operations, the mill has automated many aspects of the operation--from pumps to flotation cells to grinding mills. At the heart of the automation process is a distributed control system. Keeping a control system current to support plant operating efficiency has been a top priority at Henderson for the past 20 years.
