Influence of slimes on gravity separation of iron ore fines

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.

A Beneficiation Study on a Low Grade Iron Ore by Gravity

In this paper, a sample from Tange-zagh iron mine was characterized by gravity and magnetic separation methods. The mineralogical studies showed that hematite and goethite are the main iron-bearing minerals with insignificant amounts of FeO. The results indicated that spiral separation yields higher separation efficiency than others. The combination of spiral and multi gravity methods showed
