Limestone is part of the charge used when extracting iron from its ore. Limestone is primarily composed of a calcium carbonate compound and is not referred to as coke. When calcium carbonate decomposes as a result of the high heat inside the furnace, it reacts with sandy impurities to form what is known as slag.
In terms of non-metallic minerals, Oman is most abundant in dolomite, limestone, gypsum, clay, silica, ornamental stones and building materials, resources which are spread throughout the country. The main copper reserves, with an estimated exploration resource of around 54.5m tonnes, are located in the Sohar area of the Al Batinah region.
In 1979 the government launched Oman Mining Company, which was charged with leveraging copper reserves in the northern city of Sohar, where it also built concentrator, …
