“The Problem. The rate of flotation of solid particles determines the percentage recovery of these particles which can be obtained during a given time interval. An examination of operating data from a flotation plant shows that percentage recovery varies with the size of particle.
Many investigators have explored the problem of measuring flotation rate. In most cases the results obtained were expressed qualitatively. The results obtained by one worker were often at variance with results reported by another worker.
This investigation was undertaken with the object of (1) quantitatively measuring the rate of flotation of various sizes of particles and (2) expressing the rate in such a form that it may be used to predict percentage recovery as a function of elapsed flotation time and (3) determining the variation of flotation rate with particle size in a plant operation and comparing these results with the laboratory data. This investigation was limited to mechanical type flotation cells, as differentiated from pneumatic type cells”—Chapter I, page1.
