Iron Ore production in the Pilbara Rio Tinto
Ore car dumping Once the train arrives at the port the ore cars go through the car-dumper. The ore cars are rotated and the ore flows out into bins and then is discharged onto conveyors. Stockpile The ore is stockpiled according to product type and the quality control plan. The travelling stackers create 250m long stockpiles. Rotary The first step of physical beneficiation is crushing and grinding the iron ore to its liberation size, the maximum size where individual particles of gangue are separated from the iron minerals. A flow sheet of a typical iron ore crushing and grinding circuit is shown in Figure 1.2.2 (based on Ref.
