When the iron ore is extracted from the mine, it must undergo several processing stages. 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.

Screening is the passing of material through definite and uniform apertures is the only true and accurate means of grading to a required particle size. Air separation and hydraulic classification depend upon gravity and particle shape, and result in the segregation and retention of material of higher specific gravity and lower surface area irrespective of size.

Iron Ore (fines) Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of magnetite (Fe 3 O 4 ), hematite (Fe 2 O 3 ), goethite (FeO (OH)), limonite
