Six steps to process iron ore. 1. Screening. We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing. This step prevents overloading the crusher and increases its efficiency.

The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. …

The compression strength in wet iron ore green pellets is described in earlier textbooks [1], [3], [4], [5] by the well-known capillary theory and the Rumpf equation (Eq. (1)) [6]. It describes the agglomerate tensile strength at the capillary state, at about 90% filling degree, when a fully movable liquid is used as a binder.
