2021-1-28 Pyrite flotation separation and encapsulation in tailings dams is proposed as a viable way to chemically stabilize tailings. Characterization of potential acid mine generation in tailings led to an innovative process in which acid-generating pyrite is separated by flotation from the coarse tailings and incorporated into the slime zone.

2019-1-15 The beneficiation flowsheet at Bernic Lake involved dense media separation, pre-flotation of amblygonite, magnetic separation and flotation as illustrated in Fig. 10. The feed size to the dense media separator was −12 + 0.5 mm in which a mixture of ferrosilicon and magnetite with media density of 2.7 was used as a media.

Froth Flotation of Iron Ores - article.sapub
2012-1-2 With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a century’s practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore.

Froth Flotation of Iron Ores - Publications
the most popular flotation route in iron ore industry, the direct flotation of iron ox ides still appears desirable for some low grade iron ores that contain a vast amount of quartz. For example, at Republic Mine, Michigan, U.S.A., a hematite ore is upgraded from 36.5% Fe to 65.4% Fe with a Fe recovery of 82.5% using the direct flotation route.

2021-8-21 After scrubbing, separation of the insolubles may be done with cyclones, siphon-sizers or wet screens, while the secondary separation is usually accomplished with hydro-separators, cyclones, and thickeners (Arsentiev and Leja, 1977). Desliming by flotation of insoluble slimes from the ore in two stages is also practiced (Banks, 1976).
