Flotationofiron ore Iron oreminerals, particularly hematite and goethite, are beneficiated by combination of size fraction, pre-concentration andflotationin stages ( Fig. 12.47 ).Ironores require removal of silicate impurities of a finer size byflotationfor higher grade products of +60% Fe.
Flotationof non-sulfide minerals is more difficult than that of sulfide minerals. The main reason is that non-sulphide ores usually have high water solubility, and the useful minerals and gangue minerals are usually of similar types, with a small difference in surface properties.
Magnetic separation and flotation are the two commonly used iron beneficiation processes and selecting the most effective process to treat low-grade ore depends mainly on the mineralogical structure of the ore especially the aggregation of Iron with gangue minerals [5] .

Jan 15, 2019· This technique cannot substitute the necessary beneficiation stages of magnetic separation and flotation prior to the treatment of iron ore as a feed for iron making. The purpose of this technique is to provide a preliminary removing approach of waste gangue, which can efficiently decrease the energy consumption of the further grinding of iron ore by reducing the amount of iron ore feeding.
Deposits of low grade and high-phosphorusironores are spreading globally, however, the usage of this kind of deposits in the manufacturing of steel bounded because of the high-phosphorus content as well as depression ofironin which affect the quality of the produced steel. The Bajrawiairon oredeposit is one of the largest in Sudan but it only contains (35.5% Fe) and undesirable amount of ...
Sep 25, 2018· These techniques are used in various combinations for the beneficiation of iron ores. Iron ore is normally beneficiated utilizing the principles applied in separation of the materials by the gravity, floatation, and magnetic methods. Enrichment of ores utilizing the gravity concentration method is one of the oldest and most economic techniques.
