What Is Iron Ore Beneficiation? (with pictures)Feb 21, 2021 · Iron ore mining often focuses on looking for hematite deposits known as red iron ore, and magnetite, as they have naturally weak magnetic fields that aid in their purification. Hematite, however, responds better to the flotation process in iron ore beneficiation than magnetite, so it is the preferred type of ore.

iron ore the increasing demand of iron ore at home and abroad further stimulates the development of the benefication of iron ore. as one of the leading enterprises in domestic mineral processing industry, xinhai has been dedicated commitment to the research and development of iron extraction process and equipment for more than 20 years. beneficiation of iron ore mineral processing &metallurgycrushing is done in the conventional manner in 2 or 3 stage systems to approximately all minus ¾ inch which is considered good feed for subsequent wet rod and ball mill grinding. the primary rod mill discharge at about minus 10 mesh is treated over wet magnetic cobbers where, on average magnetic taconite ore, about 1/3 of the total tonnage is rejected as a nonmagnetic tailing requiring no further treatment. the magnetic product removed by the cobbers may go direct to the ball mill or alternately may be pumped through a cyclone classifier. cyclone underflows usually all plus 100 or 150 mesh, goes to the ball mill for further grinding. the mill discharge passes through a wet magnetic separator for further upgrading and also rejection of additional nonmagnetic tailing. the ball mill and magnetic cleaner and cyclone all in closed circuit produce an iron enriched magnetic product 85 to 90% minus 325 mesh which is usually the case on finely disseminated taconites. see full list on 911metallurgist.com the finely ground enriched product from the initial stages of grinding and magnetic separation passes to a hydroclassifier to eliminate the large volume of water in the overflow. some finely divided silica slime is also eliminated in this circuit. the hydroclassifier underflow is generally subjected to at least 3 stages of magnetic separation for further upgrading and production of additional final nonmagnetic tailing. magnetic concentrate at this point will usually contain 63 to 64% iron with 8 to 10% silica. further silica removal at this point by magnetic separation becomes rather inefficient due to low magnetic separator capacity and their inability to reject middling particles. magnetic separation on average ores with 25 to 30% iron results in about 1/3 of the total tonnage ending up in final concentrate. see full list on 911metallurgist.com the ironconcentrate as it comes off the magnetic finishers is well flocculated due to magnetic action and usually contains 5055% solids. this is ideal dilution for conditioning ahead of flotation. for best results it is necessary to pass the pulp through a demagnetizing coil to disperse the magnetic floes and thus render the pulp more amenable to flotation. feed to flotation for silica removal is diluted with fresh clean water to 35 to 40% solids. being able to effectively float the silica and iron silicates at this relatively high solid content makes flotation particularly attractive. for this separation suba flotation machines of the open or freeflow type for rougher flotation are particularly desirable. intense aeration of the deflocculated and dispersed pulp is necessary for removal of the finely divided silica and iron silicates in the froth product. a 6cell no. 24 freeflow flotation machine will effectively treat 35 to 40 ltph of iron concentrates down to the desired li see full list on 911metallurgist.com a cationic reagent is usually all that is necessary to effectively activate and float the silica from the iron. since no prior reagents have come in contact with the thoroughly washed and relatively slime free magnetic iron concentrates, the cationic reagent is fast acting and in some cases no prior conditioning ahead of the flotation cells is necessary. a frother such as methyl isobutyl carbinol or heptinol is usually necessary to give a good froth condition in the flotation circuit. in some cases a dispersant such as corn products gum (sometimes causticized) is also helpful in depressing the iron. typical requirements may be as follows: armac 12..0.100.15 lbs/ton gum #9072..1.0 lbs/ton heptinol0.025 lbs/ton one operation is presently using aerosurf mg98 amine at the rate of .06 lbs/ton and 0.05 lbs/ton of mibc (methyl isobutyl carbinol). total reagent cost in this case is approximately 5½ cents per ton of flotation product. see full list on 911metallurgist.com the high grade iron product, low in silica, discharging from the flotation circuit is remagnetized, thickened and filtered in the conventional manner with a disc filter down to 8 to 10% moisture prior to treatment in the pelletizing plant. both the thickener and filter must be heavy duty units. generally, in the large tonnage concentrators the thickener underflow at 70 to 72% solids is stored in large turbine type agitators. tanks up to 50 ft. in diameter x 40 ft. deep with 12 ft. diameter propellers are used to keep the pulp uniform. such large units require on the order of 100 to 125 hp for thorough mixing the high solids ahead of filtration. see full list on 911metallurgist.com in addition to effective removal of silica with low water requirements flotation is a low cost separation, powerwise and also reagent wise. maintenance is low since the finely divided magnetic taconite concentrate has proven to be rather nonabrasive. even after a years operation very little wear is noticed on propellers and impellers. a further advantage offered by flotation is the possibility of initially grinding coarser and producing a middling in the flotation section for retreatment. in place of initially grinding 85 to 90% minus 325, the grind if coarsened to 8085% minus 325mesh will result in greater initial tonnage treated per mill section. considerable advantage is to be gained by this approach. freeflow suba flotation is a solution to the effective removal of silica from magnetic taconite concentrates. present plants are using this method to advantage and future installations will resort more and more to production of low silica iron concentrate
