Nov 26, 2014 Iron Ore Pellets and Pelletization Process Pelletizing of iron ore was started in the 1950s to facilitate the utilization of finely ground iron ore concentrates in steel production. For the pelletizing of iron ore there are two main types of processes namely, the straight travelling grate (STG) process and the grate kiln (GK) process.Chat Online
The Iron and Steel sector has been looking at alternative methods to utilize the low grade iron ore fines for iron making so that there is optimal utilization of the available iron ore resources. The growth of the Steel Industry over the years, especially in China, despite the depletion of high grade Iron Ore.Iron ore and steel producers utilize beneficiated low-grade ores rather than direct shipping ores. Water pollution, as suggested by Profes-sor Miller, could likely be shown to rank high as a cost item in the pelletized iron ore production process, as could also air pollution. An examination of.Iron Ore Pelletizing Bentonite Karben Bentonite Iron Ore Pelletizing Bentonite Bentonite is commonly used in pelletting of iron ore Bentonite plays an important role in using degradable iron ores with low grades upon pelleting While activated calcium bentonites swell about 5-6 times of their volume Sodium bentonites can swell up to 25-30.May 18, 2017 Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high-grade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine granulometry is produced, and thus iron agglomeration.
