CATIONIC FLOTATION OF SILICA AND APATITE FROM OXIDIZED ...

Mar 07, 2019 · The NatFlot flowsheet can produce higher concentrate iron grades than the SFDF flowsheet with much lower amine collector usage. At a 64% total iron concentrate grade, the NatFlot process used 0.23 #/T of amine compared to 0.60 #/T with the SFDF process, a reduction of 62% amine. The effect of starch as a flotation depressant is shown in FIG. 7.

Recovery of Iron Ore Tailings byColumn Flotation

The concentration of iron ore by flotation is a technique consolidated worldwide for mineral particles ranging from 10 to 250 μm [1]. In Brazil, all the main pellet-feed producers use re- verse flotation, being the tailing made up mostly of quartz and a concentrate constituted of iron oxides and iron hy- droxides.

Introduction to Mineral Processing

The froth, enriched in copper and molybdenum, is removed from the flotation roughers and scavengers. This enriched material is now called the rougher concentrate or cleaner feed. The combined rougher-scavenger concentrate may be 5% Cu and 0.06% Mo (a concentration factor of 3 to 10 times is typical).
