Philippine Phosphate Fertilizer Corporation (PhilPhos) is a fertilizer company based in Makati, Metro Manila [1] which is partly-owned by the government of Nauru. Its headquarters is located at the Pacific Star Building [ 1 ] which was also built by the Nauru government.
Phosphate is also used in animal feed supplements, food preservatives, anti-corrosion agents, cosmetics, fungicides, ceramics, water treatment and metallurgy. The production of fertilizer is the largest source responsible for minerals mined for their phosphate content.
The small island nation of Nauru and its neighbor Banaba Island, which used to have massive phosphate deposits of the best quality, have been mined excessively. Rock phosphate can also be found in Egypt, Israel, Palestine, Western Sahara, Navassa Island, Tunisia, Togo, and Jordan, countries that have large phosphate-mining industries.
The term phosphate is also used in organic chemistry for the functional groups that result when one or more of the hydrogens are replaced by bonds to other groups. These acids, together with their salts and esters , include some of the best-known compounds of phosphorus, of high importance in biochemistry , mineralogy , agriculture , pharmacy ...
The construction industry is the number one user of phosphogypsum in 2020, with 10.5 Mt used as concrete set retarder and 3.5 Mt used in drywall. [13] It is also used as a chemical feedstock for producing sulfates , and as a soil conditioner similar to regular gypsum. [ 14 ]
Phosphate is an inorganic anion of phosphoric acid OP(OH) 3. There are also organophosphorus compounds with the formula OP(OR) 3. Subcategories.
Phosphorus from plant sources is therefore better suited to ruminants, but is still used to a lesser extent than phosphorus provided by inorganic sources. The ruminant's phosphorus requirements are dictated by the needs of the microbial population in the rumen, with the phosphorus being necessary for cellulose digestion and protein synthesis .
