Abstract
An improved spray apparatus for the froth flotation of a liquid-solid slurry, e.g., water-containing coal particulate, is disclosed. The initially high velocity of a spray of the slurry prior to its contacting the surface of liquid in a froth flotation cell is significantly reduced through a double deflection arrangement associated with the spray nozzle. This reduction in the velocity of the spray results in a more efficient froth flotation process.
