Cast iron has already been mentioned above. This section deals with the types of iron and steel which are produced as a result of the steel-making process. Wrought iron. If all the carbon is removed from the iron to give high purity iron, it is known as wrought iron. Wrought iron is quite soft and easily worked and has little structural strength.

pig iron, and the pig iron composition is given as 4% carbon 0.5% silicon, 0.1% phosphorus, 0.02 % sulphur, rest is iron. And ore composition is also given an ore is 90 % Fe 2 O 3. It is quite good kind of ore, 90% Fe 2 O 3 means total iron is 63 percent, because Fe 2 O 3 contains 70 % iron 30 % oxygen from stoichiometry.
Iron is the 4th most abundant element in the Earth's crust and it exists mostly as an oxide because it is easily oxidized in air. Iron has 16 oxides and among these, hematite is the oldest known. Hematite is a red-brown solid that is extremely stable under ambient conditions. It is often the end-product of all other iron oxide transformations.

Iron ore pellets are made from both magnetite and hematite ores. Hematite ores are concentrated using a flotation process. Pellets include a mineral binder that represents about 2% by weight.
Iron ores are rocks and minerals from which metallic iron can be extracted. India has large iron ore reserves. It occurs in various geological formations but major economic deposits are found in volcano-sedimentary Banded Iron Formation (BIF) from the Precambrian age. Magnetite is the finest iron ore with a very high content of iron up to …
Hematite is an Iron ore which is a dark red rock from which we get iron. It has a brown or red colour with an earthly lustre. It is the most important iron ore worldwide and is found in sedimentary and igneous rocks. Iron is basically found in four major types namely Magnetite, hematite, limonite, siderite.

Hematite's significant iron content is reflected in the deep red color of this rare mineral. It occurs in a variety of colors in igneous, metamorphic, and sedimentary rocks. The ancient Greeks were so fascinated with this gem that they named it Haima, which means "blood" in Latin. It also can be found in granite and serpentine rocks.
