ABSTRACT A very good separation of unburned carbon from fly ash was achieved with a laboratory flotation machine by employing a mixture of 4-dodecylphenol (DDP) and hexadecane (HXD) as a collector. No other reagent was required. Good results were obtained by recleaning either the concentrate or the tailings in two-stage flotation tests.
Complete and incomplete separation. In some cases, separations require total purification, as in the electrolysis refining of bauxite ore for aluminum metal, but a good example of an incomplete separation technique is oil refining. Crude oil occurs naturally as a mixture of various hydrocarbons and impurities. The refining process splits this mixture into other, more valuable mixtures such as ...

The pulp preconditioning using a stirred tank is important to strengthen the separation efficiency of coal fly ash in the flotation process. The turbulence characteristics and the turbulence length scale under different rotation speeds in the stirred tank were studied using large eddy simulation (LES).
Methods for increasing the amount of cenospheres in a fly ash sample are disclosed. The cenospheres are obtained in a dry state by using air as the "fluid" media for separation. In one version, the invention is a two step process, that is, screen by size followed by density separation such as in a fluidizing vertical column by density.
