Analytical Methods Available for Process Monitoring

Influent concentrations and residual concentrations of cationic surfactants, anionic surfactants, cationic polyelectrolyte, anionic polyelectrolyte, proteins, colloids, oxygen, ozone, detergents, suspended sohds, and so on, in the adsorptive bubble separation systems can be determined by the analytical methods reported in the literature (82,127-149). 

Important flotation process terminologies are briefly introduced in this section (1,75,124). 

Activators Activators selectively react with particles to cause the collector to surface. The classic example, as mentioned above, is the use of copper sulfate for the activation of zinc sulfide so that it can be collected by standard sulfide mineral collectors. Another example is the surfacing of lead carbonate, copper carbonate, and copper oxide with the use of sodium sulfide so that collection is also possible by the sulfide collectors. 

Air Dissolving Thbe or Retention Tank A metal tank in which the water flow and compressed air are held under high pressure for several minutes to allow time for the air to dissolve into water. 

Air to Solid (A/S) Ratio A/S is the ratio of the pounds (or kilograms) of air available for flotation and the pounds (or kilograms) of suspended solids to be floated. The A/S ratio is independent of flotation surface area.
