    rock and to a size range suitable to be floated (10 - 200 microns). 2. Creating a rising current of air bubbles in the pulp. 3. Making conditions favourable for the desired mineral particles to adhere to air bubbles. 4. Forming a mineralized froth on the surface of the ore pulp. 5. Removing the froth from the flotation cell or vessel.

    Flotation - Mineral Processing Metallurgy

    As a rule, a pulp containing particles larger than 48 mesh (0.295 mm.) is not suitable for flotation, nor is it common for the ore to be ground to a product finer than that at which 95% will pass through a 200-mesh screen (0.074 mm.). The size of the finished material usually lies between these two limits.

    Introduction to Mineral Processing

    The particle size to which the ore is ground depends on the nature of the ore. The grind must be fine enough to liberate the mineral grain from associated rock, but producing too small a particle size is both expensive and detrimental to recovery. Froth flotation is generally limited to size fractions between roughly 65 and 100 mesh.

    The effect of particle size distribution on froth

    Aug 31, 2017  Particle size distribution effects on froth stability quantified using air recovery. • A steady-state flotation system is developed to focus on particle size effects. • Fine particles result in higher air recoveries, but only at high air rates. • Changes in particle size require different air rates to maximise mineral recovery.

    Principles of Froth Flotation SpringerLink

    A light mineral such as coal (density circa 1.4) can be floated at 10 mesh, provided the bubble system on which it is borne is developed as a quiet layer of froth. Random changes of direction, acceleration, and collision may tear too large a particle out of its bubble. At the other end of the flotation size
