Ammonium sulfate preparation from phosphogypsum

Ammonium sulfate is a mixed fertilizer which contains nitrogen and sulfur nutrients (FAO, 2003, Tisdale, 2002). The ammonium sulfate provides the ideal solution that has a quick sulfate release tied in with the season-long availability of degradable sulfur (Hoeft et al., 1985, Dudal, 2002).

Ammonium sulfate - Wikipedia

2019-10-30  Uses. The primary use of ammonium sulfate is as a fertilizer for alkaline soils. In the soil the ammonium ion is released and forms a small amount of acid, lowering the pH balance of the soil, while contributing essential nitrogen for plant growth.

Ammonium Sulfate - Swenson Technology

Production. Ammonium sulfate is made by treating ammonia, often as a by-product from coke ovens, with sulfuric acid: 2 NH 3 + H 2 SO 4 → (NH 4) 2 SO 4. Ammonium sulfate also is manufactured from gypsum (CaSO 4 2H 2 O). Finely divided gypsum is added to an ammonium carbonate solution.
