A visit was made to the Amax Lead Company, Buick, Missouri to evaluate control methods in use. The company was engaged in the beneficiation of lead ore, processing 7500 tons per day of a complex sulfide ore containing about 9% lead. The Amax Buick facility was involved in crushing and screening, grinding and classification, lead and zinc selective flotation, thickening, and dewatering. The system consisted of two cone crushers with related screens operating in closed circuit with the necessary conveyor belts to handle the ore. A good-housekeeping program was in effect, with efforts to remove residual dust from floors by wet sweeping and washing down as needed. All crushing and screening operations were regulated from a control room located in the crushing facility which included a motor control panel, annunciator system, and indicators for major-equipment operation. Crushed ore was weighed by a Ramsey conveyor scale. Ore levels in the two fine ore bins were measured by Milltronics ultrasonic level devices. The grinding circuit was an automated operation in which the primary control objectives were to effectively control the particle size of the cyclone overflow product and maintain an optimum circulating load. The author recommends the establishment for inclusion in an in-depth study.
