iron ore pelletization process ppt

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 1,200 °C (2,190 °F)).

Direct reduced iron process

Iron Ore can look like many things depending on what grade the ore is if it is a high grade such as Hematite (70.0%) or Magnetite (72.4%) then the ore will have a silver gray type but if the ore has a lower iron content like Goethite (62.9%) or Siderite (48.3%) then it is more likely to look like the type of rock that it was mined from.

IRON ORE PELLET PRODUCTION AT LKAB

Sep 08, 2014· The configuration of iron ore pellets as packed spheres in the blast furnace allows air to flow between the pellets, decreasing the resistance to the air that flows up through the layers of material during smelting. This is the reason that iron ore is referred in the form of pellets rather than in the form of finer particles. 3.
