TankCell flotation units are built to last. For instance, Outotec rotors and stators have proven to be the most wear-resistant available. The wide range of available cell sizes enables a compact, economical, and efficient plant design without risk of short circuiting, even for today's high-tonnage operations.

flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water.The flotation process was developed on a commercial scale early in the 20th century to remove very fine mineral particles that formerly had gone to waste in gravity concentration plants.

Froth flotation is a process for selectively separating of hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Buoyancy (/ ˈ b ɔɪ ə n s i, ˈ b uː j ə n s i /), or upthrust, is an upward force exerted by a fluid that opposes the weight of a partially or fully immersed object. In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid. Thus the pressure at the bottom of a column of fluid is greater than at the top of the column.

The buoyant force is the upward force exerted on an object wholly or partly immersed in a fluid. This upward force is also called Upthrust. Due to the buoyant force, a body submerged partially or fully in a fluid appears to lose its weight, i.e. appears to be lighter. Following factors affect buoyant force: the density of the fluid.
