The teeter bed is constantly aerated by injecting compressed air and a small amount of frothing agent
into the fluidization water.
MIBC (methyl isobutyl carbinol), a widely used frothing agent
, was used.
The rate of accumulation of the frother in the foam and the amount accumulated may be correlated with the gas dispersion conditions, and particularly with the bubble surface area flux in the flotation cell, the surface activity of the frothing agent and its rate of adsorption.
The distribution of the surfactant at the gas/liquid interface of a bubble is influenced by the surface activity of the surfactant, rate of transport to the surface, surface transport mechanisms, concentration of the frothing agent in the solution, motion of the bubble and physical properties of the liquid.
The CCC values for several frothing agents have been determined using the University of Cape Town (UCT) Bubble Size Analyzer.
Scientists at Louisiana State University (Department of Dairy Science, 111 Dairy Science Building, Baton Rouge, LA 70803) have determined that storage and handling are the factors that mostly affect milk's performance as a frothing agent
in hot beverages.
The stirring action also shears the air into small bubbles, which are stabilized by the addition of a frothing agent
to the water phase.
A range of alcohol-based and soluble glycol-based frothing agents
are available to suit a wide range of conditions, together with of depressants based on guar, quebracho, mimosa, dextrin and other modified starches, CMC, plus anionic, nonionic and cationic synthetics.
The first is to adsorb excess frothing agents
resulting in better flotation circuit control.
They are also used to stabilize the resulting polymer latex and others are used as frothing agents
To reduce the quantity of material which needs ultra-fine grinding, and to control the extent of sulphide decomposition, the pulp is then subjected to flotation using copper sulphate, xanthate, and frothing agents
The materials are also used to stabilize the resulting polymer latex and others are used as frothing agents
