Flotation machines, in general, may be categorized into four different classes: (i) mechanical or conventional cells; (ii) energy-intensive pneumatic cells;(iii) column cells; and (iv) froth separators. Of these,mechanical Sotation cells have dominated the mineral industry since the early days of Sotation and account for a signiRcant amount of minerals processed. The aim of this article is to describe the operation and design of mechanical Sotation cells.
The froth Sotation process is commonly employed for the selective separation of a mineral species from a liquid}solid suspension of both valuable and unwanted gangue mineral particles. The valuable mineral species (which needs to be separated) is rendered hydrophobic by controlling its surface chemistry to provide the potential conditions for the attachment of the particles to air bubbles. The bubbles and particles are made to interact with each other inside a Sotation machine. The Sotation machine, depending on its operating conditions, provides an environment for the bubble}particle attachment and permits levitation of bubble}particle aggregates to the froth. The manner in which bubbles
and particles interact with each other depends on the cell operating conditions and the type of Sotation machine used.
