Flotation of Bentonite

1. Slurry adjustment and flotation agent to participate: its purpose is to result in the difference in the nature from the mineral surface, which alter the wettability with the mineral surface, adjust the selectivity of mineral surface, to ensure that some mineral particles could be coupled to the gas saturation, and Some can’t be attached to the bubbles.

2. Agitation and caused lots of bubbles: through flotation inflatable stirring, inducing the formation with the slurry within the dispersion of air bubbles, or induce to be dissolved in the air to create a slurry of micro full precipitation.

3. Bubble mineralization: mineral particles to selectively put on the bubbles, which is the most elementary act of flotation process.

4. Mineralized foam layer formation and scrapings: mineralization of bubbles rising for the lower area of the flotation pulp surface to create mineralized full foam layer for the bubble concentration of useful minerals, concentrates its scraped off and become (within the mine ) products. Not an end in mineral flotation tank remains in order to achieve the goal of sorting. Usually float the mineral flotation operation is advantageous minerals, what are known as positive flotation flotation process, whereas the gangue mineral float is called overturn flotation.

Bentonite Processing Plant

There are two methods of bentonite processing.

The dry process: bentonite – picking – drying – crushing – drying – grinding – classification – packing.

The wet process: pulping – degritting – classification – dehydration – drying – grinding – packing.

Generallly, bentonite is grinded into powder with 100 mesh, 150 mesh, and 200 mesh.
