Variables Affecting Iron Pellet Properties
Data on the influence of alumina and silica are therefore primarily of interest for assessing the likely effects of uncontrollable changes in the gangue content of iron ore used as pellet plant feed. Lime and Blaine index are variables which can be controlled at the feed preparation stage of a pellet plant.
(PDF) Iron Ore Pelletizing Process: An Overview
The use of binders for iron ore pelletizing is required to: (a) increase the pellet strength before heating – green strength; (b) prevent the collapse of the pellets during firing, when the ...
ALTERNATIVE BINDERS TO BENTONITE FOR IRON ORE …
iron ore, water and a binder are balled in a mechanical disc or drum to produce wet pellets. Bentonite is the most widely used binder in iron ore pelletizing industry. The use of bentonite is favorable in terms of physical, mechanical and metallurgical pellet properties, however, because of its acid constituents (SiO 2 …
Beneficiation Plants and Pelletizing Plants for Utilizing ...
such as sulfur and phosphorus. The iron ore and major impurities have a similar hydrophilicity; but adding a stone (collector agent) that is adsorbed selectively to either iron ore or impurities makes the surface with the adsorbed agent hydrophobic. Air bubbles are then charged from the bottom to be

Iron Ore - an overview | ScienceDirect Topics
At temperatures of approximately 1500°C, silicate and aluminate impurities from the ore and fuel combine with the flux to form a molten slag. This slag, being less dense than the molten iron, floats and can be tapped off.
Iron Ore Pellet - an overview | ScienceDirect Topics
In this route of iron making, the use of noncoking coal or natural gas is made as reductant for iron ore. The oil is used for heat hardening of iron ore pellets which is generally exploited by gas-based DRI plants. The coal-based DRI units generally require lump ore which need some electrical energy during crushing and sizing operations.
