Gypsum

Gypsum is a by-product available from Phosphoric Acid Plant and used in production of Ammonium Sulphate. GSFC has been first in the country to develop and implement successfully Phospho-Gypsum process for manufacture of Ammonium Sulphate.

This product is available in a fine mesh powder form Phosphoric Acid Plant mainly used in Agriculture as soil amendment.
Gypsum is a sedimentary mineral. It is found in layers that were formed under salt water millions of years ago. The water evaporated and left the mineral. Gypsum is composed of calcium sulfate (CaSO4) and water (H2O), i.e. Calcium Sulphate Dihydrate (CaSO4.2H2O). In Europe, the principal Gypsum quarries are located in Germany, UK, France, Spain, Italy, Poland, Russia and the Ukraine.
The main chemical substitute to natural Gypsum is FGD Gypsum(Flue Gas Desulphurisation Gypsum). It is generated by coal-fired power plants. FGD Gypsum is the end product of a wet purification procedure with natural lime that is generated according to the same laws as natural Gypsum but in a speeded-up process taking only a few hours.
Gypsum is also an indefinitely recyclable raw material. You can always reuse Gypsum because the chemical composition of the raw material in the products remains unchanged. Gypsum products can furthermore be counted amongst the very few construction materials where closed-loop recycling is possible, i.e. where the waste is used to make the same product agan
