The term phosphate rock (or phosphorite) is used to denote any rock with high phosphorus content. The largest and least expensive source of phosphorus is obtained by mining and concentrating phosphate rock from the numerous phosphate deposits of the world. In 2017, the major producers were the US, China and Morocco, including Western Sara.
Oct 17, 2019· Phosphate rock often occurs with quartz and feldspars, with economically viable deposits consisting of at least 818% P 2 O 5 and the ability to beneficiate to a maximum of 42%P 2 O 5. Sedimentary deposits occur throughout the geologic timescale, exhibiting a wide variety of chemical compositions and textures.

Dec 12, 2019· Gunaotype deposits are more common along coastlines and on islands. Most mining is by open pits and strip mining and the rock requires little processing other the the removal of the nonphosphate bearing rock and other impurities. This process involves crushing and separating impurities (sediment, bones and shells) from the phosphate rock.

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.

Phosphate rock is a grainy nondetrital sedimentary rock, which contains high amount of phosphate minerals. This rock is also denoted as phosphorite or rock phosphate.
The mining of phosphate rock (mostly from marine phosphorite deposits) for use as agricultural fertilizer (F 72) increased dramatically in the latter half of the twentieth century. In addition to fertilizer use, deforestation, increased cultivation, and urban and industrial waste disposal all have enhanced phosphorus transport from terrestrial ...
Phosphorite, rock with a high concentration of phosphates in nodular or compact masses. The phosphates may be derived from a variety of sources, including marine invertebrates that secrete shells of calcium phosphate, and the bones and excrement of vertebrates.
Jan 01, 2004· This chapter provides a review of world sedimentary phosphate deposits and occurrences. Sedimentary phosphate deposits are known on every continent except Antarctica and provide as much as 80% of the world''s phosphate. They range in age from Early Proterozoic through Holocene, although some geologic ages were more phosphogenic than others.
Mining these rock phosphate deposits is far more difficult than that in most parts of the world. Despite the complexities of the deposit, excellent results have been achieved by continuous innovations. With an annual rock handling of about 20 million tonnes, Jhamarkotra is probably the largest open cast mine in India outside the steel and coal ...
