Abstract
A froth flotation process typically used to separate particulate materials such as coal, has a mixed size feed () separated in a sieve bend () into a stream of relatively fine particles () and a stream of relatively coarse particles (). The fine particles are fed to a flotation cell () in the normal manner, while the coarse particles are mixed with wash water () and distributed onto or into the froth layer () by wash water distribution apparatus (). Alternative variations of wash water distribution apparatus able to handle coarse particles are also described.
