ABSTRACT:
A non-diluting flotation apparatus and process is disclosed which includes a single cell, or a series of multiple cells. Each cell comprises a non-agitated, flotation vessel having a submerged inlet in its upper portion for feeding a previously treated or conditioned clay or ore suspension in water. The suspension flows downward in the vessel to an outlet from which a combined product and recycle stream is taken. Thereafter, a recycle stream is separated and air bubbles are entrained into the recycle stream which is returned to the lower portion of the cell. In the cell the entrained air rises as very small bubbles, flushing certain mineral impurities removed from the clay with the air. The air and impurities form a froth atop the liquid surface and the froth is mechanically removed.
