Flotation stands out as a successful and extensively employed method for separating valuable mineral particles from waste rock. The efficiency of this process is subjected to the distinct physicochemical attributes exhibited by various minerals. However, the complex combination of multiple sub-processes within flotation presents challenges …

Bubble sizes that are discussed in the flotation area of current literature are usually in four size groups. The typical bubble size in conventional flotation machines is found to be in the range close to 1 mm, such as the data reported by several researchers which were 600–2500 μm (Rodrigues et al., 2007), 800–1600 μm (Shao, 2004), and …

This short communication presents residence time distribution (RTD) measurements and modeling in a 16 m 3 Siemens flotation cell, as the first RTD characterization in an industrial-scale pneumatic cell. The Siemens cell was installed as a pre-rougher machine in a Cu-Mo selective plant.

Abstract Flotation works very well for particles that are typically in the range 20 to 150 μm in diameter, for base metal ores. In this range, it is possible to obtain quite high recoveries in conventional flotation machines. Outside this range, the recoveries decline progressively, whether it is with the very fine or thecoarse end of the size …
