Phosphogypsum - an overview | ScienceDirect Topics

Phosphogypsum is a waste by-product from the processing of phosphate rock in plants producing phosphoric acid and phosphate fertilizers, such as superphosphate. The wet chemical phosphoric acid treatment process, or 'wet process', in which phosphate ore is digested with sulfuric acid, is widely used to produce phosphoric acid and calcium sulfate, mainly in dihydrate form (CaSO 4 · 2H 2 O):

Aug 26, 2015 · Phosphate rock extraction from its ore, and its subsequent conversion into fertilizer materials and industrial chemicals, is a relatively mature art. Single superphosphate, a mixture of monocalcium monohydrate and gypsum formed by the reaction of sulfuric acid with phosphate rock, has been used as a fertilizer since the mid-1800s.

Byproducts - The Phosphate Risk

Byproducts - The Phosphate Risk

In Florida, the phosphate rock is sent to processing plants in which it undergoes "wet process" to convert it into phosphoric acid. In the process, sulfuric acid is added to the phosphate to create phosphoric acid — which is easily absorbed by plants. Phosphogypsum (or "gypsum"), a radioactive material, is a byproduct of this process.

Phosphogypsum - Wikipedia

Phosphogypsum refers to the calcium sulfate hydrate formed as a by-product of the production of fertilizer from phosphate rock. It is mainly composed of gypsum (CaSO 4 ·2H 2 O). 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 mixing of sulfuric acid and phosphate creates gypsum (called phosphogypsum) as a byproduct. Although gypsum can be used for a variety of purposes, the EPA prevents usage of Florida's phosphogypsum because it retains low levels of radioactivity found in the host sediments. At present, phosphogypsum is piled up around the processing plant.
