Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of iron ore are at times high-grade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without concentration.

Iron ore is converted to iron by various processes. The most common process is the use of a blast furnace to extract pig iron. Pig iron comprises of about 92-94 iron and about 3-5 of carbon along with other impurities. Pig iron has limited uses so it is sent. Advances In Low Grade Iron Ore Beneficiation.
Mar 20, 2017 Pig Iron. At the beginning of the use of the electric furnace, for the manufacture of calcium carbide and ferro-alloys, experimental work was conducted in it upon the production of steel from iron ore. For many years steel and wrought iron have been produced directly from ore on a small scale in the forge, crucible, and reverberatory furnaces.
