    silica and iron recovery froma residue ofiron ore flotation

    The granulochemical analysis of the flotation residue showed that 79.0% of iron and 86.0% of aluminum are contained in the fraction below 37 µm. In desliming of the sample in 37 µm, recovery was 75.2% silica and 61.4% mass reduction. In this step, the SiO 2 content increased from 33.4% to 67.0%

    The results show that an increase of Fe content in the concentrate is observed with concomitant reduction in SiO 2 and Al 2 O 3 levels when a particular type of sodium silicate at a proper dosage is used. The concentrate of 58.89wt% Fe, 4.68wt% SiO 2, and 5.28wt% Al 2 O 3 with the weight recovery of 38.74% and the metal recovery of 41.13% can be obtained from the iron ore slimes with 54.44wt% Fe, 6.72wt% SiO 2, and 6.80wt% Al 2 O 3, when Na 2 SiO 3 with a silica …

    It is here that flotation has proven most efficient. Wet magnetic finishers producing 63 to 64% Fe concentrates at 50-55% solids can go directly to the flotation section for silica removal down to 4 to 6% or even less. Low water requirements and positive silica removal with low iron losses makes flotation particularly attractive
