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 ...

Fly ash has been tested as filler for plastics.6 For use as high-grade filler, particle size distribution, particle shape, surface chemistry, color, electrical conductivity, and other properties are critical. Based on STI's analysis of various ashes, high volume utilization of fly ash as plastic filler is not practical.
Floatation technique was used for the separation of cenosphere from fly ash. Two solvents with extremely different densities were used for the separation of cenospheres.
In searching for a low cost adsorbent for mercury removal from flue gas, this study focuses on the utilization of unburned carbons from fly ash as the substitute material for the costly activated carbons. In this first paper of the series, various separation technologies are introduced for the extraction of unburned carbon from different sources of fly ash.

gravity separation. In the present study the percentage of unburnt carbon present in fly ash is calculated by froth flotation process. The forth flotation process is a good technique to separate unburnt carbon contents in fly ash. This unburnt carbon will create the pollution in environment also decrease the efficiency of thermal plant.
The main techniques, sieving, gravity separation, electrostatic separation, froth flotation, and oil agglomeration, for separating unburned carbon from fly ash have been discussed in this section. Table 1 shows the advantages and disadvantages of methods for separating unburned carbon from coal fly ash.
The unburned carbon content of fly ash from two different power stations was greatly reduced in two-stage laboratory flotation tests by employing a collector consisting of nonylphenol and either hexadecane or fuel oil together with methyl isobutinol (MIBC) as a frother. The tailings from the first stage were recleaned in the second stage.

Flotation separation was conducted on a sort of fly ash whose ignition loss was about 17%. And the ignition loss of concentrates and tailings obtained are above 55% and below 5%, respectively ...
In this study, enrichment methods for coal fly ash (CFA) from Omsk thermal power station No. 4 (TPS-4) were investigated. The magnetite and unburned carbon concentrates were obtained by magnetic separation and flotation methods. The wet magnetic separation used in the study increased the magnetite content in the magnetic fraction from 10.48 to 12.72 wt % compared to dry magnetic separation.
