    Abstract: An improved flotation process for removal of colored titaniferous impurities from kaolin clay uses as collector a hydroxamate compound, or a mixture of compounds, having the formula ##STR1## in which R is an alkyl, aryl, or alkylaryl group having 4-28, and preferably 6-24 carbon atoms, and M represents an alkali metal, an alkaline earth metal or hydrogen. The process does not require the use of activators to make the collector adsorb selectively on the colored impurities.

    Abstract: A method for separating inorganic gangues from coal particulates dispersed in a coal refuse slurry comprises the selective flocculation of the coal refuse slurry by initially adding an anionic dispersant followed subsequently by adding an anionic flocculant, allowing the flocculating coal slurry obtained to settle and collecting a concentrated settled coal slurry having a lowered ash value. The dispersed inorganic gangues may be recovered by the addition of a cationic flocculant/coagulant with subsequent recycle of the aqueous phase.

    Abstract: A method for removing inorganic sulfides from finely ground, non-sulfide minerals is provided. A polymeric agent having a molecular weight of from about 1,000 to about 300,000 and with a plurality of xanthate groups per molecule is admixed into an aqueous suspension including inorganic sulfides and non-sulfide minerals. The polymeric agent adsorbs onto the inorganic sulfides and maintains them as a dispersion while the remaining minerals are selectively separated, as by flocculation.
