Vale is the worlds leading producer of iron ore and pellets. We are investing in technological innovations and developing initiatives to prevent and Thus, the production of pellets is fundamental to the steel production process. Where? Our mines are concentrated in Brazil, where we also operate pelletizing plants.
When used at concentration plants with combined methods of cleaning, the process of dry-concentration at initial stages makes it possible to substract up to 50%
This process generates iron ore filter cake which needs to be pelletized to be used in the steel making process. Also during the processing of high grade iron
Apr 10, 2011 Generally, iron ore falls into two categories, hematite and magnetite. The beneficiation process for taconite requires crushing, screening, Concentrate is generally the first product you get from Taconite beneficiation.
