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.
Phosphate deposits can contain significant amounts of naturally occurring heavy metals. Mining operations processing phosphate rock can leave tailings piles containing elevated levels of cadmium, lead, nickel, copper, chromium, and uranium. Unless carefully managed, these waste products can leach heavy metals into groundwater or nearby estuaries.
