Phosphorus is obtained from phosphate deposits. Phosphate ore beneficiation methods have been continuously enriched in the development. The traditional beneficiation methods include: scrubbing and desliming process, gravity separation, flotation, gravity-magnetic-flotation combined process and roasting process.
-
Scrubbing and desliming process: for ores with a high degree of weathering.
-
Gravity separation: The proportion of main gangue minerals in phosphate rock is similar to that of apatite. In industrial practice, dense medium separation is mainly used.
-
Flotation: Flotation has always been the main method for beneficiation of phosphate ore, especially for complex and difficult ores. Such as positive flotation, single reverse flotation, positive one negative (negative one positive) flotation, double reverse flotation.
-
Roasting method: It is a fairly mature method used in industry to completely remove carbonate from phosphorite ore.

There is no such compound named Phosphorus bromine. It you refer to the product formed in the reaction of phosphorus and bromine, its Phosphorus Tribromide = PBr3
Formula for phosphorus triodide?
hello, here is some information regarding phosphorus trioxide It is obtained by the combustion of phosphorus in a limited supply of air at low temperature. P4(s) + 3 O2(g) → P4O6(s) Phosphorus trioxide reacts with cold water to form phosphorous acid. P4O6(s) + 6 H2O(l) → 4 H3PO3(aq) It reacts vigorously with hot water, via a complex set of reactions, to form red phosphorus, phosphines, H3PO3 and H3PO4. dr.virag
Where is phosphorus found or obtained from?
it was obtain in germany
What results when phosphorus and si are combined?
phosphorus-doped silicon ( n-type semiconductor) can be be produced by adding phosphorus to silicon to obtain a mixture, then heating and melting the obtained mixture. Or add phosphorus to already melted silicon.
What is the word obtained after unscrambling the word horpuhposs?
The element "phosphorus," meaning "light-bearer" in Greek
How can you get Oxygen Hydrogen Nitrogen Carbon Phosphorus and Sulfur as pure elements?
Oxygen and hydrogen can be obtained by electrolysis of water. Nitrogen by liquefying air,and phosphorus and sulphur by other chemical reactions. Search the internet you'll find it!!
How was phosphorus found in nature?
Phosphorous was originally obtained from old bones. Hence the original recyclers, the "Rag and Bone Man". Today it is refined from guano, or from rock phosphate.
What is the difference between red phosphorus and white phosphorus?
White phosphorus is obtained by roasting Calcium phosphate rocks and then reducing them using silica White phosphorus reacts with air vigorously that is it burns instantly in presence of oxygen and show phophorescence property ( it emits bright luminous green light in dark in prsence of small amount of oxygen ) , hence it is stable below 125'C and red phosphorus is stable above 125'C. If you heat white phosphorus upto 125'C in absence of air you get red phosphorus. White phosphorus has 4 atoms of P linked in tetrahedral shape, where as red phosphorus have amorphous network arrangement hence red phosphorus is more stable. White P is soluble in carbon di sulfide and small amount in water, but red P is not soluble in both water and carbon disulfide. white P is used in explosives, incendiaries, bullets etc
What is the Latin name for phosphorus?
the latin name for phosphorus is phosphorus
Why is phosphorus named phosphorus?
phosphorus means "bringer of light".
Is phosphorus Ionic or convalent bond?
Phosphorus is a nonmetallic element so phosphorus-phosphorus bonds are covalent.
