Frothers for Enhanced Flotation Outcomes Froth flotation chemistry can significantly impact the flotation process, from preventing bubble coalescence, to stabilizing bubble size and particle adhesion, to increasing bubble residence time and surface area flux. Today's rapid froth flotation processes rely on alcohol- and polyglycol-based chemistries.

22/06/2021Over the past few decades, the need to process more minerals while lowering capital costs has led to an increase in the size of flotation cells, e.g., 0.03 m3 to 1000 m3. However, this increase has created new challenges in the operation and design of industrial flotation cells, particularly in terms of froth removal, because the distance the froth

The effect of flotation operational parameters on froth stability and froth recovery was studied. Froth stability was measured using a special column. To determine the froth recovery, the froth height change model and froth height exponential model were used. It was found that since the interactions between the pulp and froth zones affect the

Froth flotation commences by comminution (that is, crushing/grinding), which is used to increase the surface area of the ore for subsequent processing and break the rocks into the desired mineral and gangue, which then has to be separated from the desired mineral. The ore is ground into a fine powder.
