EP2658655B1 Aminecontaining formulations for reverse

After a reverse froth flotation step, generally the iron ore bottom fraction either contains a low level of silica but exhibits a low recovery of iron, or it exhibits high recovery of iron but contains a high level of silica. Various solutions have been proposed in the prior art to increase iron recovery and at the same time reduce silica levels.

Phosphate flotation W. R. Grace & Co. Free Patents Online

Mar 22, 1983 · It is a type of flotation known as "reverse flotation" since the tailings (quartz or silica particles) are floated, and the desired ore, namely phosphate rock particles, sink and become the concentrate. The silica is, in fact, present in a much greater amount than the phosphate rock.

Reverse flotation of silica from Kudremukh iron ore. I

Four types of ionic collectors were tested and evaluated for their performance in the reverse flotation of silica from the spiral preconcentrate of Kudremukh iron ore. A stagewise flotation was conducted by adding the reagent in three stages. Starch was used to depress hematite. Silica flotation was found to be very sensitive to the amount of ionic reagent added.
