Pelletizing Process

iron ore. His process involved grinding taconite to remove gangues and upgrading the iron ore (i.e., an ore beneficiation process). The resultant high-grade ore is in the form of fine particles, as small as 0.1mm or less, which are not suitable for sintering. This issue led to the use of pelletizing. Pelletizing plants are expected to play an

Fine Dry Grinding of Iron Ore for Pelletizing

A trend toward pelletizing iron ore at the steel plant site may be developing.
