Mining removes phosphate-rich beds and exposes organic carbon-rich waste rock to subaerial weathering. Waste rock is generated at a rate of 2.5 to 5 times that of mined ore. Individual dumps contain 6 to 70 million tons of waste-rock that is either contoured into hills, used as cross-valley fill, or used as back-fill in mine pits.
