GMC is one of largest manufacturer of Gypsum in GCC sourcing most of raw materials from Oman itself. GMC also engages in production of Limestone, Marbles, Gypsum boards and blocks. "Giving a new definition to underground"
Production is expected to start later this year at the new GE Aviation facility in Limestone County, according to a company spokesman.
Limestone is a type of rock that is used extensively in different industries such as construction and as animal feed. Aside from these basic uses, limestone is also used in mines where it provides illumination and reduces the amount of cold dust stirred by the different activities held within the mine.
The limestone is more easily ground than the clinker, which is harder, and becomes concentrated in the finest particles. Overall fineness must be higher (for equivalent performance) for fineness of the clinker fraction to be similar to OPC. This means the production rate is slowed and some additional grinding energy is required.
Limestone industry comprises companies that operate by manufacturing, production of mining or quarrying crushed and broken limestone. Limestone, often referred to as the world's most versatile mineral, is an important raw material for various industries.
Production. In the lime industry, limestone is a general term for rocks that contain 80% or more of calcium or magnesium carbonates, including marble, chalk, oolite, and marl. Further classification is by composition as high calcium, argillaceous (clayey), silicious, conglomerate, magnesian, dolomite, and other limestones.
Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore. These ingredients, when heated at high temperatures form a rocklike substance that is ground .
Limestone is a collective term for a group of sedimentary rocks that consist of at least 50 percent calcite, a mineral formed of calcium carbonate. If some of the calcium becomes replaced by magnesium, the resulting calcium magnesium carbonate rock is called dolomitic limestone.
Production. The mining of limestone begins with its extraction from deposits in mines and quarries, with many of these mines being located in the United States, as well as in parts of the African and South American continents. After extraction, limestone is tested for its chemical composition.

The production of cement releases greenhouse gas emissions both directly and indirectly: the heating of limestone releases CO 2 directly, while the burning of fossil fuels to heat the kiln indirectly results in .
