The process involves the integration of coal, a crucial energy source, contributing to the creation of coke in the electric arc furnaces, which aids in reducing iron ore to molten metal. Limestone, introduced during the steelmaking process, eliminates impurities and acts as a flux, facilitating the smoother melting and refining of the materials.
Chromite Ore: Following the discovery of around 100,000 tonnes of chromite ore at two sites in Fanja (Wilayat of Bidbid) and Al Raki (Wilayat of Yanqul), MDO has decided to proceed with their commercialization.
