Rock Mining Phosphate

The mining of phosphate rock (mostly from terrestrially emplaced marine phosphorite deposits) for use as agricultural fertilizer, begun in the midtolate nineteenth century (Cordell et al, 09), has increased dramatically since the latter half of the twentieth century (Mackenzie et al, 11) (F 72) In addition to fertilizer use, deforestation, increased cultivation, and urban and industrial waste disposal all have enhanced phosphorus transport from terrestrial to aquatic systems, often.

Rock mining phosphate. The phosphate strip mining is accomplished by various methods of stripping the materials from the ground as illustrated above The phosphate industry relies heavily on the dragline excavator to keep moving large amounts of overburden to mine the phosphate rock just beneath the surface. It takes one ton of phosphate to produce every 130 tons of grain, which is why the world mines about 170 million tons of phosphate rock every year to ship around the world and keep soils fertile Most of the world’s best phosphate reserves are gone, and those that remain are in just a handful of countries. Phosphates are the naturally occurring form of the element phosphorus, found in many phosphate minerals In mineralogy and geology, phosphate refers to a rock or ore containing phosphate ions Inorganic phosphates are mined to obtain phosphorus for use in agriculture and industry The largest global producer and exporter of phosphates is Morocco.
