Process Models And Computer Control In Milling Activities

The question of automation of concentrator operations with computer control is under increasing consideration. Some of the problems involved will be discussed from the viewpoint of the availability of the requisite, detailed knowledge of the unit operations. The justification for full-scale automation of a mill must ultimately be economic--an increase in profitability over and above the cost of instrumentation and development, Potential savings would be in three probable directions: decrease in operating labor costs by substitution of machine control; improved metallurgy through continuous effective control; and decreased operating costs by achieving higher unit capacities and process efficiencies.
