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.
For example, see Sodium tripolyphosphate. Sometimes pyrophosphate, tripolyphosphate, tetrapolyphosphate, etc. are called diphosphate, triphosphate, tetraphosphate, etc., especially when they are part of phosphate esters in biochemistry. They are also used for scale and corrosion control by potable water providers. [6]
In biological systems, phosphorus can be found as free phosphate anions in solution (inorganic phosphate) or bound to organic molecules as various organophosphates. [5] Inorganic phosphate is generally denoted P i and at physiological (homeostatic) pH primarily consists of a mixture of [HPO 4] 2− and [H 2 PO 4] − ions.
The phosphate mining industry employed 2,200 people. The value of phosphate rock mined was US$2.2 billion. As of 2015, there are 10 active phosphate mines in four states: Florida, North Carolina, Idaho, and Utah. The eastern phosphate deposits are mined from open pits. The western deposits are mined from both surface and underground mines.
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.
