Mineral Processing and Extractive Metallurgy Review, 2017. A typical high-alumina containing iron ore slime from the eastern Indian sector containing 58.13% Fe, 6.48% SiO 2, 4.9 % Al 2 O 3 and 5.35% LOI, have been evaluated to find out whether grinding of the slimes will be beneficial or not for upgrading the slime to generate pellet-grade concentrate with >64% Fe.
Desliming is an essential step for a successful separation in the cationic flotation of iron ores for similar reasons as in the anionic flotation of iron ores (i.e., the presence of slimes leads to high reagent consumption due to their high surface area; slime coatings on the larger particles, governed by electrostatic interaction, interfere ...
