Pelletizing

Pelletizing is the process of compressing or molding a material into the shape of a pellet A wide range of different materials are pelletized including chemicals , iron ore , animal compound feed , plastics, and more...

Iron mining in the United States

Iron mining in the United States began in 1608, when a ship returning from the Jamestown Colony in ia carried a load of iron ore back to England The manufacture of iron from ore apparently began in 1622, in what is now Chesterfield County, ia , but was halted when Native Americans killed everyone in the ,...

Traveling Grate Pelletizing Plant

Outotec's traveling grate pelletizing plant is the industry's leading induration technology for iron ore pellet production for a wide range of plant capaciti Based on over 60 years' experience and world-class R&D, our process...

Direct reduced iron

Process Direct reduction processes can be divided roughly into two categories: gas-based, and coal-based In both cases, the objective of the process is to drive off the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc), in order to convert the ore to metallic iron, without melting it (below ,...

Rotary kilns

Rotary kilns The final induration is accomplished in a rotary kiln, wherein the principal heat transfer mechanism is radiation from the system's main burner Grate-Kiln iron ore pelletizing system provides process flexibility...

Iron ore pelletizing systems

Iron ore pelletizing systems Iron ore fines are agglomerated into pellets and then indurated using a furnace to create iron ore pellets These are typically fed to a blast furnace or DRI plant as part of the process to make steel...

Mining industry of Nigeria

Iron ore Nigeria has several deposits of iron ore, but the purest deposits are in and around Itakpe in Kogi StateThe National Iron Ore Mining Company was founded in 1979 and given the mission to explore, exploit, process, and supply iron ore concentrate to the Ajaokuta Steel Company (ASCL) in Ajaokuta and Delta Steel Company (DCL) in Aladja...

Traveling grates

Traveling grate process Features After feeding the pellets to the traveling grate, the unit operations of green ball drying, concentrate dehydration, partial calcination, and partial induration are performed on a traveling grate, whereupon heat transfer occurs in zones of the grate from the cross flow of process gas (hot air) repeatedly passed through the ,...

The Making of Iron & Steel

Iron ore, as mined, is a combination of iron with oxygen and various other unwanted substances, generally known as "gangue" The first metallurgical step is to reduce iron ore to metallic iron, a process which is mostly carried out ....

Corex Process

In addition, the Corex process can use iron oxides containing up to 80% lump ore and uses non coking coal directly as a reducing agent In the Reduction shaft the iron ore, along with limestone and dolomite additives, is added and then reduced by reduction gas into 95% direct reduced iron, DRI [6]...

FINEX (steelmaking process)

FINEX is the name for an iron making technology developed by former Siemens VAI (now Primetals Technologies) and POSCO Molten iron is produced directly using iron ore fines and non-coking coal rather than traditional blast furnace methods through sintering and reduction with coke Elimination of preliminary processing is claimed to make the ....
