Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO4·2H2O. It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, drywall and blackboard or sidewalk chalk. Gypsum also crystallizes as translucent crystals of selenite. It forms as an evaporite mineral and as a hydration product of anhydrite. The Mohs scale of mineral hardness defines gypsum as hardness value 2 based on scratch hardness comparison.
Calcium sulfate (or calcium sulphate) is the inorganic compound with the formula CaSO4 and related hydrates. In the form of γ-anhydrite (the anhydrous form), it is used as a desiccant. One particular hydrate is better known as plaster of Paris, and another occurs naturally as the mineral gypsum. It has many uses in industry. All forms are white solids that are poorly soluble in water. Calcium sulfate causes permanent hardness in water.

The Mtwara Development Project is a major infrastructure development project involving southern Tanzania, northern Mozambique, eastern Malawi and Eastern Zambia. The goal of this project is to provide road, rail and waterway access from the surrounding region to the Port of Mtwara. The region and the corridor has been neglected by the respective governments for over 40 years and the recent discovery of oil, gas and various minerals has kick started the development of the project. A road and rail link is to be built from the port of Mtwara to Mbamba Bay on Lake Nyasa to link Malawi to the corridor and further road links into Mozambique will facilitate access to northern Mozambique.
