The transformation from traditional iron- and steelmaking technologies to green H2-based new technologies will require an improvement in the quality and purity of iron ore burden materials. Iron ore pellets are essential inputs for producing direct reduced iron (DRI), but the conventional binders, used in iron ore pelletizing, introduce gangue The TG process is indicated for treating any type of iron ore.

Waste heat from the exhaust gases of Golgohar iron ore pelletizing Plant, in Sirjan, Iran, was studied using energy analysis based on input data extracted from measurements in a 5-month period.Pelletizing is the process through which iron ore fines are transformed into an agglomerated form called “iron ore pellets” suitable for use in an iron-making furnace at a steel mill, such as a blast furnace or electric arc furnace. In its end product form, a typical iron ore pellet is roughly spherical in shape, measuring from 6 mm to 16Pelletizing Plants BOLLFILTER

Iron ore is an important raw material for steel production. According to statistics, world iron ore production increased from 1.043 Bt in 2001 to 2.93 Bt in 2012 [].Due to the increasing consumption of high-grade iron ore, the iron content in iron ore is decreasing, and these iron ores have to be finely ground and beneficiated to enrich the Another type of ore found in this country is the itabirites that have lower iron contents. Beneficiation and concentration steps are required to prepare these materials for the pelletizing process. A general view of Brazilian types of iron ores, mines, and mining companies is given in this work.Brazilian Iron Ore and Production of Pellets: Mineral

Improvement on the thermal cracking performance of pellets prepared
As the ultrafine iron ore concentrate was used to prepare green pellets, the main problem was the serious cracking during the drying process. The fine particles contacted so closely that the porosity of green pellet was only 16.68%, which finally hindered vapor diffusion, and the cracking temperature was only 370 °C.The global production of iron ore products in 2019 including China was 2346 Mt whereof 1845 Mt consisted of sinter fines, lump ore and other iron ore products and the remaining 501 Mt consisted of BF and DR pellets. Figures excluding China are for the same year 2105 Mt and 361 Mt, respectively (Löf and Löf 2020). The consumption of DR Driving investments in ore beneficiation and scrap upgrading
