In this research, the efficiency of magnetic separation methods for processing of a low-grade iron pigments ore (red ochre) has been studied. Based on the mineralogical analyses (XRD), thin section and polish studies, the reserve is an iron sedimentary deposit with an average Fe grade of %31.3. The most valuable minerals are Hematite and Goethite and main gangue minerals are Calcite …

The 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 ...

iron ore (iron oxide) into metallic iron: the blast furnace (BF), which is by far the most common, and the direct-reduction (DR) route, which accounts for just over 100 million tonnes per year (tpy), or around 8% of global primary iron production. Blast furnaces are usually paired with basic oxygen furnaces (BOFs) to …

It is a low-grade type of ore sample (±35% Fe) with high silica and calcium content (±36%). Based on the fact, that there are appreciable differences in magnetic susceptibility between the desired iron minerals and the gangue minerals, hence, it was suggested that multi-stages magnetic separation may be useful to concentrate this type of ore.

Iron ore with 63.5% iron content for delivery in Tianjin traded below the $120 per metric tonne level after briefly touching one-month highs of $129 in mid-October.
