stages and recycle lines Column flotation devices were reintroduced for mineral processing in the late1960’s in Canada by Boutin and Wheeler (1967) at which time wash water addition to the froth was used to eliminate entrainment of hydrophilic materials to the float product By the late1980’s column flotation had became a provencolumn flotation, covering pilot testing and scaleup, circuit design of selected applications, and instrumentation and control We begin with a description of the key features and concepts of column flotation KEY FEATURES AND CONCEPTS A schematic of a flotation column is shown in Figure 1 Industrial flotation columns are 614 mColumn Flotation SGS

1 Froth Flotation – Fundamental Principles

1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry The particles with attached airLithospheric Plates: The Earth's crust, together with the uppermost mantle, forms the lithosphere The lithosphere is further divided into the continental crust and the oceanic crustWhat do lithospheric plates float on? | Study
