When the ore arrives at the Fairlane Plant, it first goes to the "fine crusher" where it is reduced to gravel-sized pieces. Next, the crushed ore proceeds to the "fine ore surge," where it is stored until processing. Beneath the fine ore surge are rows of conveyor belts and hoppers known as "Mexican feeders."
