Centralized Control and Instrumentation Systems at Iron Ore Co. of Canada's Benef iciation Plant

In the last several decades, there has been a rapid •change in the concepts regarding remote control versus centralized control and operation. Proponents of local control methods felt that local operators who can see and be in close contact with equipment would provide a better class of operation. This was true until equipment manufacturers developed new and larger types of equipment. This equipment required faster reflexes and better judgment. In many cases, the local operator or attendant was not able to observe his equipment completely, due to its size and/ or complexity. At this point, the need arose for integrating equipment controls. To accomplish this, the instrument industry had first to develop the necessary sensors, pickups, transducers, etc. that could act as eyes and ears for the operator. The rapidly accelerating research and development in instrumentation and automatic control systems has made possible many new automatic control system applications. There are still many problems to be solved in this field, but the basic equipment is available to the mining industry. This paper describes the general flowsheet of one recently completed iron ore beneficiation plant, and the application of the concept of centralized control and instrumentation as applied to its processes.
