------------------------------------------------- Issues * To minimize total waiting time and stockpile re-handling costs (Keep operations costs as low as possible). * To improve productivity process and decreasing idle time of machines and labor.
-------------------------------------------------
Background * Iron Ore Company of Ontario is working in the business field of processing iron ore. * Production was scheduled on a year-round, 24 hour-per-day basis to produce over 46 million tonnes of crude ore per year, of which 21 million tonnes are high grade concentrate. * To achieve this capacity, a concentrator was built with input capacity of 1760 cubic meter of crude ore per hour, i.e. concentrator was used at full capacity at all times. * Production Process * Large drills cutting 12-metre holes into solid rock. * These holes are then filled with explosives. * Electric Shovels start to load the trucks. * Trucks carry waste material to waste dump outside the mine, while ore was carried to the crushers. * The ore enters the crushers, where large rocks were reduced in size. * The crushed ore passed by conveyor to the concentrator where it was further crushed into waste tailings and 66% iron concentrate. * The concentrate product was finally loaded on a ship and exported to Europe and North America. * Shovels * Shovels load an average of 480 cubic meters per hour per unit. * 7 Shovels were available per shift in Ore Zone, while the 8th Shovel was located at crude-ore stockpile “for less usage”. * Remaining Shovels were undergoing maintenance. * Tractors *
