ABSTRACT:
In conditioning pulp, such as ore particles carried by or in suspension in water, or other particles, conditioning prior to flotation involves the addition of one or more reagents to the pulp or the like. By this invention, an agitation and pumping zone, spaced from the bottom of the tank in which the operation is carried out, pumps pulp outwardly in swirling, circumferential streams. A conditioning reagent is supplied to the active area of the pumping zone, such as the center of the zone. The operation may be enhanced by using a pair of pumping zones, one above the other, as well as intercepting the streams of pulp radially outwardly of the pumping zones, as by a stabilizer having radially extending vanes.
