The Brazilian iron ore industry has led the world in adopting column flotation technology for reducing the silica content of iron pellets. Several companies have installed, or are in the process of installing column cells into their process flowsheets. Samarco Mineracao S.A., the first Brazilian producer to use column cells, installed columns to increase flotation capacity as part of a plant expansion program in 1990. Since that time, they have installed additional columns for the recovery of fine iron from the desliming circuit and for a recent plant expansion program. Table - 1 lists the major users of column flotation in iron ore …

What Is Iron Ore Beneficiation? (with pictures)

Raw iron ore has to be purified for use. Iron ore beneficiation is a multi-stage process that raw iron ore undergoes to purify it prior to the process of smelting, which involves melting the ore to remove the metal content. The process of iron ore beneficiation has two complementary goals and these define the methods used to refine it.
