Phosphogypsum By Radhika Sales Corporation

We are the popular exporter, distributor, supplier and trader of Phosphogypsum in Vapi, Gujarat, India. Phosphogypsum refers to the gypsum formed as a by-product of the production of fertilizer from phosphate rock. It is mainly composed of gypsum (CaSO4A.2H2O). Although gypsum is a widely used material in the construction industry, phosphogypsum is usually not used, but is stored indefinitely because of its weak radioactivity. The long range storage is controversial.

Phosphogypsum is a side-product from the production of phosphoric acid by treating phosphate ore (apatite) with sulfuric acid according to the following reaction:

Ca5(PO4)3X + 5 H2SO4 + 10 H2O a 3 H3PO4 + 5 CaSO4 A. 2 H2O + HX
where X may include OH, F, Cl, or Br

Phosphogypsum is radioactive due to the presence of naturally occurring uranium and thorium. Marine-deposited phosphate typically has a higher level of radioactivity than igneous phosphate deposits, because uranium is present in seawater. Phosphogypsum also can contain high levels of cadmium
