- Phosphate rock or
phosphorite is a general description applied to several kinds of rock
which contain significant concentrations of phosphate minerals.
- The two main sources
for phosphate are guano, formed from bird droppings, and rocks
containing concentrations of the calcium phosphate mineral,
apatite.
- Phosphate rock can be
any rock or sediment with sufficiently high concentrations of some form
of the mineral fluorapatite.
- Phosphorus-rich rock is
deposited in a body of water in which there is no oxygen; this is called
an anaerobic environment.
- Phosphate rock
occurrence ranges from nodular, residual phosphatic limestone, to vein
phosphates, and consolidated and unconsolidated
phosphatic
sediments.
- Phosphate rock is
mined, beneficiated, and either solubilized to produce wet-process
phosphoric acid, or smelted to produce elemental phosphoric acid or
smelted to produce elemental phosphorus.
- Phosphate rock is
formed in oceans in the form of calcium phosphate, called
phosphorite.
- The phosphatic rock is
characterised by filaments of wavellite, turquoise and quartz.
- The effectiveness of PR
is largely determined by the extent of PR dissolution in moist
soil.
- The separation of
phosphate rock from impurities and nonphosphate materials for use in
fertilizer manufacture consists of beneficiation, drying or calcining at
some operations, and grinding.
- A green house
experiment was carried out on a simulated crop rotation system of upland
rice-soybeanmungbean to determine the effect of P-derived from different
phosphate rock (PR) sources and TSP using 32P.
- Commercial phosphate
rock is usually sedimentary in origin and is used primarily as a plant
nutrient.
- Several scientists the
world over have been trying to develop1,2 low-cost phosphatic
fertilizers.
- Indian scientists were
successful in testing low-grade phosphate rocks3–5 for direct
application.
Nitrates and phosphates are the main agronutrients mined
by current sub-Saharan small scale agricultural practices.
- Biofertilisers produced
with phosphate rock (PR) plus sulphur (S) inoculated with
Acidithiobacillus can promote plant growth and increase available P in
tropical soils.
- Deflourinated phosphate
rock is the source of phosphate used in animal feed and feed
concentrates.
- Technically and
economically feasible beneficiation technology is used for processing
dolomite pebbles which is needed to recover phosphate value.
- The Florida phosphate
industry has been practicing the current flotation technique for
concentrating phosphate minerals for half a century.
- Flotation is one of the
most efficient techniques applied for phosphate upgrading. Desliming of
flotation feed is a critical pre-request step for successful
phosphate/gangue separation by flotation.
- Researches on their
structures by means of XRD, IR and EPR technique revealed that their
crystal structures changed considerably, improving their activity and
preventing the fixation of available phosphorus in the soil, and
consequently, greatly improved the bioavailability and became the main
cause of the increase of biomass.
- The United States is
the world's leading producer and consumer of phosphate rock.
- China, the United
States and Morocco are the world's largest miners of phosphate
rock.
Most of the U.S. and world phosphate rock resources are widely
distributed marine phosphorite deposits.
- Total capacity of the
phosphate rock industry in the U.S. is 56 million tons, with mines
currently operating at about 90 percent of capacity.
- There are markets such
as those of Malaysia and Brazil, where directly applied phosphate rock
makes good sense from an agronomic or economic point of view.
