This invention relates to the beneficiation of iron ores by froth flotation More particularly, the invention relates to a two-stage flotation process suitable for use on fines such as are found in the overflow from iron ore washer plants in waste products from heavy media separation processes and on those ores which must be finely ground in order to unlock the iron minerals from the gangue...
Iron ore flotation shows good performance for the concentration of oxidized ores with low iron content, allowing the reduction of silica found in magnetic concentrated and therefore it is the most suitable process for the production of concentrates intended for metallurgical processes that use a direct reduction process Iwasaki, 1983 IWASAKI ....
Nov 23, 2021 0183 32 Reagents in iron ores flotation ScienceDirect Queiroz verified that, for certain itabirite ore types, the use of attrition allows the increase of the mass recovery to the slimes and flotation concentrate fractions and the decrease of iron grade in the flotation tailings, iron grade in the slimes and SiO 2, Al 2 O 3 and P grades in the concentrate, resulting in higher figures for Gaudins ....
Iron ore is the key raw material for steel production enterpris Generally, iron ore with a grade of less than 50 needs to be processed before smelting and utilization After crushing, grinding, magnetic separation, flotation, and gravity separation, etc, iron is gradually selected from the natural iron ore...
