Jul 18, 2013· AbstractThe Ghorabi iron ore is composed mainly of goethite, hematite and quartz minerals. Chemically, four-fifths of the ore (80·65%) are iron oxides (44·10%, 34·30%Fe) and silica (36·81%). The size distribution of the ore indicates that iron is concentrated in the fine fraction (>38% in fraction −53 μm) while silica is concentrated in the coarse fraction (>40% in fraction +53 μm).
