Marangoni Effect

Marangoni_effect

Gibbs surface elasticity, which is commonly referred to as the Marangoni effect, is the surface tension gradient along the air-liquid interface that acts to preserve the film thickness and to prevent bubble coalescence as shown here.

Coarse and Fine Particle Flotation Recovery

Coarse

In The Days of gravity concentration, the art of ore dressing developed on the cardinal principle of saving the values at as coarse a size as possible. Flowsheets were designed which featured an alternation of crushing and concentrating operations. Thus an ore might be crushed to ½ inch, jigged to yield a finished concentrate and a […]

Guide to Flotation Cells in Mineral Processing

Cell

The flotation process and related flotation cells are widely used for treating metallic and nonmetallic ores and in addition, it is receiving an ever widening application in other industries. A greater tonnage of ore is treated by flotation than by any other single process. Practically all the metallic minerals are being recovered by the flotation process […]

Flash Flotation Cell

Classifier Circuit

More profit can be earned by using the Flash Flotation Cell in the grinding Circuit. This machine has been designed especially for the recovery of floatable minerals at a coarse size as soon as the mineral is free; together with the finer sizes. Even though many ores require fine grinding to make the maximum recovery, […]

Flash Flotation Cell and Flotation Banks

Unit Flotation Cell

Flash Flotation Cell The “Sub-A” Flash Flotation Cell, when installed in the circuit between the ball mill and classifier, makes possible the quick recovery of coarse free mineral, which is a vital factor in economic mill operation. Slime losses from overgrinding are reduced to a minimum with the use of the “Sub-A” Unit Flash Flotation […]
