Flotation Cell Circuit Flotation Cell Maintenance

Frothers & Froth Flotation ArrMaz

During the flotation process frothers help create the ideal hydrodynamic conditions such as bubble size and gas holdup required within the pulp in the flotation cell They generate froth that is stable enough to hold collected minerals on top of the pulp mobile enough for removal and decays quickly to assist with downstream operations These characteristics play an important
