bentonite and filter cake moisture in iron ore pelletizing

Iron ore slurry filtering solutions

In pelletizing plants that operate with wet grinding to reduce the particle size of the ore prior to the balling/pelletizing process, it is necessary to dewater the slurry exiting the grinding mills to lower the moisture content in the ore. The pelletizing of iron ore normally requires from 8% to 10 % moisture depending on the ore characteristics.

Center for Advanced Sustainable Iron & Steel Making

While many bentonite characterization methods have been proposed, none have proven to have a good correlation with binder performance. In this study, it was discovered that this problem was largely caused by very high levels of dissolved calcium compounds being retained in the moisture of iron ore concentrate filter cake.
