Characterization of Iron Ore Green Pellets by Scanning Electron Microscopy and X-ray Microtomography
Cryogenic scanning electron microscopy (cryo-SEM), image analysis (IA) of SEM micrographs and X-ray microtomography (XMT) were used to obtain new information about the morphology of iron ore green pellets in this work. Cryo-SEM and freeze fracturing was used to observe entrapped air bubbles and arrangement of particles around the bubbles and in the matrix of wet green pellets. The observations ...
متن کاملMultimodal Microscopy for Ore Characterization
Modern microscopes of all kinds (optical, electron, scanning probe) are controlled by software and have digital image acquisition. This setup allows many integrated tasks to be run under the control of automation routines like, for instance, specimen scanning and automatic focusing. Additionally, some microscopes can be fully automated. Thus, it is possible to integrate specimen scanning, image...
متن کاملAir bubbles in iron ore green pellets due to flotation reagent: characterization by scanning electron microscopy and X-ray microtomography
Iron ore concentrate is enriched by flotation prior to form iron ore green pellets in order to reduce phosphorus content in the ore concentrate. A flotation reagent is used in this process and it is known to incorporate air bubbles and eventually deteriorate the strength of the pellets. These bubbles were therefore characterized both qualitatively and quantitatively by cryogenic scanning electr...
متن کاملMicrowaves Applied to Carbothermic Reduction of Iron Ore Pellets
Results of reducibility tests of reduction conducted on iron ore pellets with carbon are presented in this work. Work done is centered on reduction kinetics using carbon as reducing agent with conventional heat supply (heat transfer process) compared with reduction kinetics where heat is supplied by microwaves to the whole volume. Ore used in this work is called "Alzada" which has reducibility ...
متن کاملCharacterization of Sangan low-grade iron ore and its processing by dry low-intensity magnetic separation
In Sangan iron mine nearly two million tons of low-grade iron ore has been extracted and deposited in the mining site and currently no action is made on them. On the other hand, the mining site is located in the semi-arid region and wet processing has been restricted due to water shortage. In this research, the upgradation of Sangan low-grade iron ore from mine B has been performed by dry low-i...
