Flotation is a widely employed method in mineral processing and beneficiation for effectively separating mineral particles.

GKN Aerospace promoted its businesses in transparency systems, advanced de-icing systems, emergency flotation equipment and complete fuel systems at HAI, 2005. In the field of flexible fuel cells, GKN Aerospace has a worldwide reputation with products qualified for over 40 types of aircraft.

Column flotation cells, like mechanical cells, are used to perform mineral separations. Column cells do not use mechanical agitation (impellers). Instead, mixing is achieved by the turbulence provided by the rising bubbles. ... Gold Flotation & Columns. In another unique application, hot (120°F) flotation of hot leach tails definitely favored ...

In the conventional flotation cell, the detachment of particles from the bubbles due to turbulence is the main reason for the decline in the coarse particle recovery (De et al., 2007, Fuerstenau et al., 2007).However, turbulence is imperative in the flotation cell to bring about bubble particle collision, keep particles in suspension, and disperse …

Launders: Launders are troughs located at the top of the flotation cell. They collect the froth and direct it to the froth removal system.
