Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of Mangnetie (Fe3O4, 72.4% Fe) hematite (Fe2O3 69.9%) goethite ((FeO(OH), 62.9% Fe) Limonite (FeO(OH) n(H2O) 55% Fe) siderite (FeCO3, 48.2%, Fe) Ores containing very high quantities of hematite or magnetite, typically greater than about 60% iron, are known as natural ore or direct shipping ore, and can be fed directly into iron-marking blast furnaces. Iron ore is the raw material used to make pig iron which is one of the main raw materials to make steel 98% of the mined iron ore is used to make steel. In 2011 the Finacial Times quoted Christopher LaFemina, mining analyst at Barclays Capital, saying that iron ore is " More integral to the global economy than any other commodity except perhaps oil".

Copper cathode is� a form of copper that exhibits purity of more than 95%. It is the primary raw material utilized in the production of copper rod, which is employed in several industries. Pure copper exhibits excellent electrical conductivity. In order to remove impurities from copper ore, it undergoes two processes, smelting and electro-refining. Copper cathodes are used in the� manufacturing of continuous cast copper rods which are further used for the wire, cable and transformer industries. They are also used for the manufacturing of copper tubes for consumer durable goods and other applications in the form of alloys and sheets. MOQ 5,000MT Supplied from Africa
