Froth Flotation Principles

 · The tool "Floatation" since its general introduction some thirty years ago, has made rapid strides until it is now used for concentrating more ores than any other process. The "Sub-A" itself came into being in 1927 and in the intervening years its development has kept pace with the advancing technique in the ever-widening field of ore dressing.
