Reduction Kinetics of iron ore pellets and effect of binders

2012-7-10  Upgrading naturally found iron ores is accomplished by grinding the ore into fine particles so that the iron containing materials can be liberated from unwanted gangue. This beneficiation process leaves the iron ore in a finely ground state that is not easily transported or readily processed in steel making facilities. Therefore, it is necessary to agglomerate the fine ground material into pellets using

Growth Kinetics of Metallic Iron Phase in Coal-based

iron directly from oolitic iron ore, where the iron minerals in the ore are directly reduced to metallic iron phase, which are subsequently liberated by grinding and separated from the slag by magnetic separation. Several research efforts have been made in coal-based reduction, demonstrating that it is a feasible method to make use of oolitic iron ore as a mineral resource for ironmaking.

An innovative approach for determining the grinding

2021-1-22  The grinding experiment was operated with the Anshan type iron ore. The results of the laboratory grinding experiment indicated that the media size ratio, space-filling factor, and material ball ratio had a significant influence on the grinding kinetics of the iron ore sample. (2) The average grinding rate increased with a decrease in media size.
