beneficiation of iron ore slimes by gravity concentr

Influence of slimes on gravity separation of iron ore ...
Iron ore fines contain so-called slimes that act negatively on particle beneficiation due to elevated viscosity, leading to contamination of the final product, poor dewatering, and inferior materials handling. Cyclones provide a low-cost solution to removing the slimes, while also concentrating the coarser particles. The reality, however, is that there is significant misplacement of slimes ...
