What Are the Main Uses of Iron Ore?

12-04-2020  Iron ore is used primarily in the production of iron. Iron is used in the manufacturing of steel. Steel is the most used metal in the world by tonnage and purpose. It is used in automobiles, airplanes, beams used in the construction of buildings and thousands of other items.

Hopper car - Wikipedia

A hopper car or hopper wagon is a type of railroad freight car used to transport loose bulk commodities such as coal, ore, grain, and track ballast. Two main types of hopper car exist: covered hopper cars, which are equipped with a roof, and open hopper cars, which do not have a roof. This type of car is distinguished from a gondola car in that it has opening doors on the underside or on the sides to discharge its cargo. The development of the hopper

02-04-2010  Original purpose of the iron-ore sintering process is to agglomerate fine ores into lump burdens for blast furnace (BF).

The principle of transformer iron core

The core's role is to strengthen the magnetic coupling between the two coils. In order to reduce the eddy current and hysteresis loss in the iron, the iron core is formed by lamination of painted silicon steel sheets; there is no electrical connection between the two coils, and the coils are wound by insulated copper wires (or aluminum wires).

purpose far exceeds the norm of 100 ppm which would reduce the fertility of the land, besides enhances the water pollution. (d) Economic consideration : Most of the hematite based iron ore processing plants in the Jharldiand, Chattisgargh and Orissa states were originally designed to

Mine stockpile design to minimise environmental impact

The exported ore is destined for blast furnaces, whose efficient operation depends upon the ore being of consistent composition, not only in iron but also in the major contaminants, including silica, alumina and phosphorus. The quality of the ore therefore depends upon each shipment closely matching the target composition vector.
