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 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 ]

The negotiations to pursue rights to the phosphate involved four parties: the British and German governments, the newly reorganised Pacific Phosphate Company, and Jaluit-Gesellschaft (a German mining company that had been ...
The majority of the inorganic feed phosphates used in the EU and worldwide are calcium phosphates in different forms (mono-, di- and monodi-calcium phosphates) but also magnesium phosphates, sodium phosphates and even ammonium phosphates are used in animal nutrition. The end-product quality depends on the treatment and production process.
It uses a specially fluidized and siliconized monoammonium phosphate powder. [1] ABC dry chemical is usually a mix of monoammonium phosphate and ammonium sulfate, the former being the active component. The mix between the two agents is usually 40–60%, 60–40%, or 90–10% depending on local standards worldwide.
Low phosphate levels are an important limit to growth in a number of plant ecosystems. The vast majority of phosphorus compounds mined are consumed as fertilisers. Phosphate is needed to replace the phosphorus that plants remove from the soil, and its annual demand is rising nearly twice as fast as the growth of the human population.
In 1972–1973, Philippines was beset by rice production shortfalls resulting from the series of typhoons and floods and fertilizer shortages spawned by the oil crisis.The resulting fourfold drop in rice production prompted the government to directly intervene in the operations of the fertilizer industry through the issuance of Presidential Decree (P.D.)
