How to manage tenacious froths in a froth pump

Mineral froths are generally divided into large bubbles that are easily broken and very small tenacious bubbles that are difficult to separate from the slurry liquid.

As ore grades declined everywhere, the flotation of the minerals produced increasingly tenacious froths, which caused pumping difficulties for operations.

Grinding out more and more fines and ultrafine results in smaller bubbles froth. And a flocculant is added to the slurry to lock the air into more tenacious bubbles.

Operators can use best practice design to design a more appropriate froth pump circuit or reduce flocculant of fines.
