Three large mining machines, called draglines, excavate the remaining overburden from the mine bench down to the top of the phosphate ore and place the overburden in previously mined out areas. This process, called stripping, exposes the phosphate ore, which is then excavated by the draglines and placed on the mine bench where it is stockpiled.
