Read MoreThe 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 ...
Read Moremost of the Indian iron ore mines are operated by selective mining for maintaining a high grade of iron ore (Fe>60%). Presently the circuit adopted for processing of iron ores has limitations in reduction of alumina. In particular it can not handle huge quantity of low grade ores and fines available from earlier workings (Singh et al. 2004).
Read MoreThe consumption of iron ore has increased rapidly over the past decade due to the tremendous growth of the iron and steel industry. The depletion of high-grade iron ore resources makes it inevitable to utilise the existing low-grade iron ores/fines/tailings with proper beneficiation to meet the present specification and demand.
Read MoreAt present, there is no reasonable way to use ferric silicate. Therefore, iron silicate in ore does not emphasize recovery. Although iron silicate can be recovered by mineral processing method, because iron grade in iron bearing silicate minerals is low, it will reduce the total concentrate grade greatly, which is unreasonable in economy.
