Dec 23, 2008· Abstract. The action of activators that include oxyethylated groups is investigated. Supplying PAV1 surfactant before the collection agent intensifies flotation in a number of ways: by changing the physicochemical properties of the diffuse layer of coal particles (reducing the unit surface charge); by increasing the emulsification of the apolar reagent; by promoting more orderly structure of ...

Many valuable minerals, such as coal, are beneficiated by froth flotation. Coal is an extremely valuable natural resource in the United States because of its relatively abundant supply. Energy shortages together with the availability of abundant coal reserves has created a new interest in the use of coal as an alternate or primary energy source.
