Improving reducibility of iron ore pellets by optimization ...
It has direct influence on improving productivity and lowering energy consumption in iron making process. The reducibility of iron ore pellets of a specific chemistry can be improved by the optimization of physical parameters such as induration temperature, improving size distribution of fines, improving apparent porosity etc. In this study, the reference pellet is prepared in a typical plant ...
Iron Ore Pelletizing Process: An Overview
Bentonite is an effective, widely used binder in the iron ore pelletizing process. Its low price is an important factor for its extensive use. However, bentonite incorporates silica and alumina, which are undesirable contaminants to pellets. Additionally, it is a natural material with variable composition depending on its origin. Obtaining a suitable binding effect requires a relatively large ...
Usage of HighLOI Iron Ore Fines in Pellet Making | SpringerLink .
08/06/2019 · High LOI in iron ore fines has an adverse affect during pellet induration process. HighLOI iron ore fines are required for detailed laboratory pelletization studies and are used in pellet making. The received iron ore is martite–goethitic and hematite–goethitic form of ore with high LOI content. The iron ore consists of % Fe, % SiO2, % Al2O3, % moisture and % LOI. From ...
Direct reduced iron
Process. Direct reduction processes can be divided roughly into two egories: gasbased, and coalbased. In both cases, the objective of the process is to remove 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)).
(PDF) Cooling process of iron ore pellets in an annular ...
In this period, air flow, heat transfer, and iron ore pellet oxidation take place at the same time [6][7][8]. Finally, the pellets are cooled, the cooling air is heated, and the waste heat is recovered [9][10]. The technological flow chart is shown in Fig. 1. The outlet and the inlet of an annular cooler are neighbors and are separated by a partition. The inlet is at the roof and the outlet ...
Iron Ore Pelletization
The Pelletizing Process. The production of iron ore pellets from fines to finished product can differ based on a variety of factors. As such, it's important to note that the process described here is a generalized approach subject to many variations. In general, three primary phases occur in iron ore pelletizing: Mixing/Preconditioning. The mixing step sets the stage for the remainder of the ...
