Gypsum
-Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical
formula CaSO4•2H2O. It is used as a fertilizer.
-Pure gypsum is a white to transparent mineral, but sometimes impurities color it grey, brown,
or pink. It interferes with another mineral called anhydrite.
Uses
-Manufacture of wallboard, cement, plaster, soil conditioning, a hardening retarder in Portland
cement.
-Varieties of gypsum known as "satin spar" and "alabaster" are used for a variety of
ornamental purposes; however, their low hardness limits their durability.
Types of Gypsum
1-Alabaster: It consists of fine crystalline granular blocks.
2-jbset: It is a non-pure landfill and Flour granules
3-selenite: It is one of the finest types of gypsum and It consists of transparent monocrystals.

Rock Salt
-This is the common name for the mineral "halite". Its chemical formula is NaCl. You might
know this substance as table salt. and... Actually, rock salt is not K2SO4; it is NaCl. It can have
impurities of gypsum (CaSO4) and sylvite (KCl) but it is very rare to find potassium sulfate as a
mineral, although occasionally polyhalite (K2Ca2Mg(SO4)4.2H2O) is found associated with rock
salt deposits.
-It is typically formed by the evaporation of salty water (such as sea water) which contains
dissolved Na+ and Cl- ions
Uses
Table salt is essential for human life. A large amount of the commercially mined rock salt is
prepared for human consumption. Rock salt is also applied to road beds in cold climates to
help reduce the freezing point of water on the road, thereby allowing it to not freeze-over at 0
deg, In chemical industries.
