Sep 10, 2017 As a major hub of mineral mining in the world, and an untapped wealth of natural resources, Africa has a vast and booming mining industry. The industry not only provides employment to millions of African citizens, it is also an important source of earnings to most African nations through export.
There are four main mining methods underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.
The Chiria mines in Saranda are believed to hold the largest deposits of iron ore in Asia. In the 85,000 ha of the Saranda division, 28 leases for iron ore mining exist in about 9,300 ha. The past few years have seen an increase in mining. Thousand of trucks jam the

moratorium effectively put the mining industry at a standstill as a thousand of applications for new mining contracts were put on hold. Minings contribution to the economy is small, ranging merely from 0.6 to 1.0 percent of the GDP during the said period. In 2012, mining accounted for merely 0.7 percent of the GDP.
Iron Ore. Iron (Fe) is a metallic element which constitutes about 5% of the Earths crust and is the fourth most abundant element in the crust. Iron ores are rocks from which metallic iron can be economically extracted. The principal iron ores are hematite (Fe 2 O 3) and magnetite (Fe 3 O 4 ).
In-situ mining, which is treated under a separate heading in this chapter, is a special case that combines aspects of mining and processing but does not require the excavation, comminution, and waste disposal steps. The major components can also be combined innovatively, such as when in-situ leaching of copper is undertaken after conventional ...

shale) and iron (steel mill scale or iron ore) in cement kilns. The cement burning process (preheater) is rapidly changed and accordingly the heat consumption rate is remarkably improved. Preheater tower is the heat exchanger where the heat of kiln exit gas is transferred to the incoming material (Kiln feed).
Steelmaking Overview. Steelmaking is the second step in producing steel from iron ore. In this stage, impurities such as sulfur, phosphorus, and excess carbon are removed from the raw iron, and alloying elements such as manganese, nickel, chromium, and vanadium are added to produce the exact steel required.
