Removing Clay From Iron Ore

A Study on Removal of Clay Minerals from Barbil Region

2020-8-31  The removal of the ultrafine clay minerals from the iron ore fines helps to make the downstream processes such as grinding, beneficiation, and pelletization easier. Approximately 80–90% of the clay minerals may be discarded by using screw scrubber at the beginning before being fed to the subsequent beneficiation process.
