The exploited natural resource of Somalia is mainly uranium. However, there are many unexploited reserves of bauxite, copper, iron ore, tin, gypsum, salt, natural gas, and probable oil reserves. The country's mineral sector is largely underdeveloped and only makes a small contribution towards exports and economy in general. Overview of Resources
This gypsum is a byproduct of the desulphurisation of the flue gases of coalfired power stations. Sulphur dioxide emission control systems remove sulphur from combustion gases using 'scrubbers'. One particular type of scrubber that uses either lime or limstone reagent system produces 'FGD gypsum' which is chemically nearly identical to mined natural gypsum.
Plaster of Paris is dehydrated gypsum. Gypsum is a naturally forming nonmetallic mineral, found as a rock or sand composed of % calcium sulphate and % water by weight. Its chemical formula is CaSO 4 • 2H 2 O. Gypsum is found naturally in most parts of the world. In addition to mined gypsum there is 'Byproduct' gypsum.
· Used in both plasterboard and cement, gypsum is a key component of the construction industry.
