The main phase of the Mongolian iron ore pellets is hematite, with a porosity of 25%-30%.
Pelletizing of Iron Ore Concentrates
The iron ore concentrates subjected to pelletizing tests represent four different Canadian sources. Extensive test work was carried out on three samples from the Adams Mine near Kirkland Lake, Ontario. The major proportion of the equipment used in batch balling and pellet evaluation is quite common to most well equipped mineral dressing laboratories.
Iron Ore Pellets and Pelletization Process – IspatGuru
Nov 26, 2014 · Iron ore fines with comparatively high Al2O3 content exhibit different pelletizing characteristics. As for the firing of hematite iron ores, more heat is required to be supplied from external sources due to the absence of the following exothermic reaction of oxidation of magnetite.
Introduction to Iron ore Pellets and Pelletizing processes ...
Pelletizing is a process which involves mixing of very finely ground particles of iron ore fines having a size which is less than 200 mesh (0.074 mm) with additives like bentonite and then shaping them into near oval/spherical balls having size in the range of 8 mm to 16 mm in diameter by a pelletizer and hardening the balls by firing with a fuel.
(PDF) Iron Ore Pelletizing Process: An Overview
The iron ore pelletizing process consists of three main steps: 1. Pelletizing feed preparation and mixing: the raw material (iron ore concentrate, additives. —anthracite, dolomite—and binders are prepared in terms of particle size and chemical. specifications, dosed, and mixed together to feed the pelletizing process;

Types of Iron Ore: Hematite vs. Magnetite | INN
Hematite ore is found throughout the world, but the most utilized deposits are in Brazil, Australia and Asia. Hematite ore has been the primary type of iron ore mined in Australia since the early 1960s. Approximately 96 percent of the continent’s iron ore exports are high-grade hematite ore,...
Fine Dry Grinding of Iron Ore for Pelletizing
A trend toward pelletizing iron ore at the steel plant site may be developing. This evolution would probably result in utilizing various blends of ore feed which could have wide variations in their grindabillty. Effect on Pellet Quality. Good pellet quality depends on a large number of variables many of which are inherent in the ore.
Iron processing - Ores | Britannica
Iron processing - Iron processing - Ores: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite (Fe2O3), which is ...
A further study on adsorption interaction of humic acid on ...
First of all, magnetite and hematite were the two main components in the iron concentrates. As reported, the pH IEP of magnetite and hematite falls between 5.4 and 9.0 [38], [46]. When using the MHA binder in the pelletizing process, a small amount of HA was adsorbed onto the iron concentrate particle surfaces.
