For example, a sulfide ore might float very well at 90 to 120 microns, but not at 50 or 150 microns. The research to date has identified two main reasons for the upper limit on floatable particle sizes. First, coarser particles tend not to have as
A series of separate flotation experiments were performed using cell charges consisting only of the particle size under question. Thus a K value for each size i was determined with the values indicated. If there were no interactions between sizes in a flotation charge consisting of a mixture of sizes, it should be possible to estimate the over all R and K of the mixture by taking a weighted

Note: The requirement for flotation for persons weight is 2/15 of the persons weight or 0.1333 times the persons weight. But in the Guidelines the USCG uses 1/4 or 0.25 times the persons weight to provide a safety factor. This provides a safety factor of 2 or twice the amount of flotation for persons weight. If you use 2/15 you will have a smaller amount of flotation.

Effects of bubble size and particle size. Froth drainage. Effects of cell geometry. Particle shape texture: Flotation generally operates on particles formed by the breakage of mineral ores. The breakage is an essentially random process so that the resulting particles areplex shape and structure. The particle shape after crushing is random, angular, elongated and ill defined, but after
