reverse flotation required

Imhof et al. (2005) detailed the use of pneumatic flotation cells totreat a magnetic separation stream of a magnetite ore by reverse flotation to reduce the silica content of the concentrate to below 1.5%. From laboratory testing, they claimed that the pneumatic cells performed better than either conventional mechanical cells or column cells.

    Oxide and Reverse Flotation Mining SGS

    In reverse flotation, properreagents induce the pay minerals to become hydrophobic (water repelling) and the waste minerals to become hydrophilic (water attracting). Aeration is added through spargers at the bottom of the flotation cell. The bubbles attract and then float the waste minerals, leaving the pay minerals in the underflow.
