There are a number of physicochemical properties of iron oxide mineral phases (eg goethite, hematite and magnetite) that can be prudently exploited to enhance their processing efficiency. Recent iron ore studies on the upgrading of highgoethite iron ores have highlighted that the knowledge of the various phases of both iron oxide and gangue minerals is critical to the economic processing of
Dry beneficiation of lowgrade goethiterich iron ore fines by air classification, reduction roasting and magnetic separation, in Proceedings Iron Ore 2019, pp 766785 (The Australasian Institute of Mining and Metallurgy: Melbourne).
Lowgrade iron ore received from the West Singhbhum area of Jharkhand state in India was used to develop a beneficiation flow sheet to remove alumina (Al2O3) and silica (SiO2) from the ore to get iron (Fe)rich product for steel plants. Mineral characterization showed that the main mineral constituents present in the head sample are goethite, limonite, hematite, quartz, clay and gibbsite.

on ultrafines recovery plant tailings revels that, there was an escape of martite, goethite and hematite in tailings. Again an attempt was made in 2010 by conducting inhouse and external study to recover escaped iron ore bearing minerals from ultrafines recovery plant on line tailings using column flotation

explores to develop a strategy for beneficiation of the waste manganiferous iron ore fines for its suitable utilization in pellet making. 2. Materials and Characterization Materials The manganiferous iron ore sample received from Southern part of India was used in the investigation assaying % Fe, % Mn, % SiO 2 and % Al 2O 3.
The form and occurrence of gangue minerals in different ore types has been described and compared to enable optimisation of beneficiation flow sheets. Characterisation of magnetitebearing lumps and fines allows comparison of magnetites ores from different origins and facilitates valuable information related to the production of lump or fine ore products.
The principal separation in iron ore beneficiation, therefore, is between the iron minerals, hematite and/or magnetite, and silica, principally in the form of quartz. The use of flotation, either alone or in combination with magnetic separation, has been well established as an efficient method for rejecting silica from these iron ores.

#0183;#32;The effect of mineralogy and texture on the beneficiation of goethitic ores from two different origins is highlighted. Sample A having % Fe with % loss of ignition (LOI) indicates the presence of vitreous and ochreous goethite, martite and microplaty hematite as the major minerals.
The Ghorabi iron ore is composed mainly of goethite, hematite and quartz minerals. Chemically, fourfifths of the ore (80#183;65%) are iron oxides (44#183;10%, 34#183;30%Fe) and silica (36#183;81%). The size distribution of the ore indicates that iron is concentrated in the fine fraction (gt;38% in fraction 53 m) while silica is concentrated in the coarse fraction (gt;40% in fraction +53 m).
