Iron ore concentrate pellets have the potential to fracture and abrade during transportation and handling, which produces unwanted fine particulates and dust. Consequently, pellet producers characterize the abrasion resistance of their pellets, using an Abrasion Index
Iron ore in a finely ground state is not easily transported or readily processed .Thus it is necessary to agglomerate the fine ground ore into pellet using binders. Inorganic binders introduce silica which decreases the final ore content of the pellet. Hence organic binders were developed.
the iron ore industry, methods need to be developed for producing domestic iron ore pellets that are economical and have superior metallurgical properties that will result in coke reduction during blast furnace smelting. Since iron ore concentrates consist of finely divided particles, they must be
What are Pellets ? Pellets are ground iron ore fines converted to spherical shaped balls Have good physical properties for mechanical transportation over long distances Have excellent metallurgical properties (similar or better than lump iron ore - CLO) Vital raw material for all types of iron making
Feb 01, 1972 Transportation of Iron Ore by Slurry. 720566. Transportation of solid materials by pipeline is, of course, not a new development. In the 1950s a 108 mile pipeline was constructed from Cadiz, Ohio to Cleveland transporting approximately one million tons per year of coal to a public utility plant. This line was discontinued in the 60s having served its purpose of forcing a reduction in the rail rate.
Direct-reduced iron (DRI), also called sponge iron, is produced from direct reduction of iron ore (in the form of lumps, pellets or fines) by a reducing gas produced from natural gas or coal. The reducing gas is a mixture majority of hydrogen (H2) and carbon monoxide (CO) which acts as reducing agent. This process of directly reducing the iron ore in solid form by reducing gases is called direct reduction.

The production of granulated iron ore is generally done dry and without water. Its feed is iron ore with a grade of about 50% and the product is iron ore with a grade of 68-60% in two or three dimensional classes. In the feed factory, it is crushed in two or three stages and divided into different granulation classes by a sieve.

Iron ore pellets are produced by a process in which the iron ore is mixed with additives necessary to adapt the desired chemical composition, and they are then pelletized in rotatory disks. The resultant elements are pellets which are taken to a straight grate furnace, where they undergo a thermal process, receiving additional mixtures of polymers or acrylic copolymers, polymers and vinyl ...
