2013-5-23In 2010 world iron ore pellet production was 388 Mt. It could be argued that the current pellet production process has been enabled by the use of binders practical experience has shown that it would be nearly impossible to agglomerate iron ore using rotary drums and discs without using a binder

D. Zhu in Iron Ore 2015. In a DR process iron ore pellets andor lump iron ores are reduced by a reducing gas to produce DRI or hot briquetted iron HBI. Depending on the generation of the reducing gas two different DR processes are commercially available gas-based and coaloil-based. In the gas-based DR process the reducing gas is

2020-5-19Direct reduced iron DRI also called sponge iron is produced from the direct reduction of iron ore in the form of lumps pellets or fines to iron by a reducing gas or elemental carbon produced from natural gas or coal.Many ores are suitable for direct reduction. Direct reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting

These iron ore pellets are transported from Sweden to Norway for shipping. In 1902 a train line was built all the way to Narvik for this purpose. At the time this was the most northern train line in the world. The trains using this route pull up to 68 rail carts and transport around 33 million tons of iron ore per year
