The resulting magnetite concentrate contains un-liberated magnetite (magnetite particles that are still attached to other minerals) which requires further milling so that the magnetite can be liberated and extracted. Un-liberated magnetite is usually larger than liberated magnetite, so the two can be separated according to particle size.
A three-dimensional computational fluid dynamics (CFD) model was developed to study the hydrogen reduction of magnetite concentrate particles in a laboratory flash reactor representing a novel flash ironmaking process. The model was used to simulate the fluid flow, heat transfer, and chemical reactions involved. The governing …
