1. Phosphogypsum is a moist, fine powder with a free water content of ca. 20 - 30 % and considerable amounts of impurities, the exact impurities and their amounts depending on the rock and the specific process. The radioactive substances present in small amounts in sedimentary phosphate rock are partly transferred to the phosphogypsum as 226Ra, leading to slightly increased radioactivity of such gypsums. About 1.7 t of gypsum is obtained per tonne of raw phosphate, corresponding to 5 t of gypsum per tonne of phosphorus pentoxide produced.
2. Calcium sulphate (CaSO₄) is a white solid that occurs naturally as a mineral anhydrite. It is found more commonly as dihydrate, called gypsum (CaSO₄·2H₂O). When heated, gypsum loses water at 128°C to give a hemihydrate (2CaSO₄·H₂O), also known as plaster of Paris.
Calcium sulphate is sparingly soluble in water and makes water permanently hard. CaSO₄ is used in the manufacture of certain paints, ceramics and paper. Its naturally occurring form is used in sulphuric acid manufacture.
Gypsum is the cheapest and the most useful material in reclamation of sodic soils.Calcium, solubilized from gypsum, replaces sodium, leaving behind the watersoluble sodium sulphate, which is leached out as a result of the following reactions in the soil:
Since both reactions are reversible, adequate leaching arrangements have to be made to remove sodium sulphate.
The application of about 40 t/ha of gypsum in Nevada (USA) was seen to increase water infiltration and the depth of water penetration substantially. These two measures increased hay yield up to 2.3 t/ha per year.
Gypsum requirement (GR) is the amount of gypsum necessary to be added to reclaim soil and is calculated using the formula:
The gypsum requirement is equivalent to (Na_x)×4.50 metric tons of gypsum per hectare for a 30 cm fixed depth, where Na, is the milliequivalent of exchangeable sodium to be replaced by calcium from the added gypsum.
