The surface of our planet is rich in terrestrial iron oxides such as magnetite and hematite (many of which will stick to a magnet), dark black rocks such as basalt, and many different types of man-made metallic by-products such as runoff (slag) from old smelters, and castoff iron How iron is made material, manufacture, making, history,Historically, iron was produced by the hot-blast method, or later, the anthracite furnace. Either way, the fundamental activity in iron making involved a worker stirring small batches of pig iron and cinder until the iron separated from the slag.

Iron ore is the most common meteor-wrong. Magnetite especially is very magnetic (hence its name) and hematite may or may not be mildly magnetic. Both these minerals may possibly be distinguished from meteoritic material by a characteristic known as 'streak'. You can test the streak very simply.Iron and Steel Slag Statistics and Information,In the production of iron, the blast furnace is charged with iron ore, fluxing agents, usually limestone and dolomite, and coke as fuel and the reducing agent. The iron ore is a mixture of iron oxides, silica, and alumina. From this and the added fluxing agents molten slag and iron are formed.
The optimum conditions for recovering iron by oxidizing roasting and magnetic separation are as follows: calcium oxide content of 25 wt.%, mixed gas flow rates of CO2 and CO of 180 and 20 mL/min, oxidizing roasting at 1323 K for 2 h, grinding the modified slag to 38.5–25.0 μm and magnetic separation at US1277523A Magnetic iron product and method of making,The improved method of making an iron product having superior magnetic properties, which consists in subjecting a refined molten iron in which manganese, sulfur, and phosphorus have been reduced to 0.05 per cent. or less when taken in the aggregate, and carbon to 0.02 per cent. or less to the action of a vacuum, treating the molten iron with a
Iron and steel slag, also known as ferrous slag, is produced by adding limestone (or dolomite), lime and silica sand to blast furnaces and steel furnaces to strip impurities from iron ore, scrap and other ferrous feed materials and to lower the heat requirements of the iron- and steelmaking processes. Ferrous slag forms as a dominantly calcium silicate melt that floats on top of the molten,
