During dry processing, hard massive ore results in generation of coarser fraction known as sized ore having size from 10 to 40 mm and used in blast furnace while soft goethite-rich mineral tends to generate fine fraction known as fine ore having size below 8–10 mm. Dry processing of iron ore is popular for treating hard massive hematitic ores; however, fines generated during processing of

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.

Typically, iron ore fines from the region will display moisture contents of between 13% and 16% during the wet season. In addition, it is normal for the upper surfaces of any stockpiled material to appear relatively dry during the dry season period but wet at increasing depths throughout the stockpiled material.

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
