ABSTRACT:
Aeration flotation bar comprising a shaft mounted in a tank for rotation about a vertical axis and having a plurality of wedge configured bar members. Air through the shaft is distributed lengthwise through each wedge bar member simultaneously and from each wedge bar member is emitted as a fine jet through multiple jet bores formed in the trailing surface of the wedge bars. The fine air jets create a large mass of fine air bubbles which in the aggregate provide more surface for material such as coal or other flotable materials to adhere to thereby increasing the reclamation output of the tank or cell and increasing the efficiency of the tank or cell. In addition, the location of the fine jets are such that the fine air jet streams act on the area of the tank or cell where sanding is most likely to occur and thus eliminate or minimize the sanding tendency.
