extraction of 3Mtpa DSO (Direct Shipping Ore) from the concession area. Iron ore product was to be transported from the mine site to the Port of Buchanan, from where it was then to be exported. Transportation of the ore was via a combination of truck (haul road) and rail, with the start of the rail route at Yekepa in Liberia. Design Services
Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel98% of the mined iron ore is used to make steel. In 2011 the Financial Times has speculated that iron ore is quot;more integral to the global economy than any other commodity, except perhaps oil quot;.

How Is Iron Extracted From the Earth? Reference
Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.
Increasing iron ore demand, coupled with the depletion of highgrade hematite ores in the United States, after World War II led to development of lowergrade iron ore sources, principally the utilization of magnetite and taconite. Ironore mining methods vary by the type of ore being mined.
