SPARGING SYSTEM FOR COLUMN FLOTATION ABSTRACT A system for sparging aerated water into a column for the froth flotation of minerals, and located in the lower portion of the column, consists of water and air supply headers connected to a supply of pressurized water and air, respectively. The headers comprise a number of water and air passages, each having shut off means. A multiplicity of sparger tubes is arranged, in one or more horizontal planes, either radially towards the column centre or parallel to each other from opposite sides of the column. Each sparger pipe comprises a mixing tee attached to a water passage and an air passage, and a perforated portion provided with a number of small openings. The number of openings in each pipe is determined by the cross-sectional area covered by the sparger pipe. The openings may be arranged upwardly and/or downwardly at an angle in the range of about 5° to 90° from the horizontal. The openings are preferably arranged in a single row and directed vertically downwardly, or in two parallel rows and directed radially downwardly at an angle of 5° to 75° from the horizontal. Each opening is provided with a wear-resistant material, preferably in the form of an insert and preferably made of tungsten carbide, to reduce erosion of the openings. The number of openings is chosen such that the air bubbles exit from the openings and rise in the column substantially evenly distributed over the entire cross section of the column.
