Tsunekawa, Masami published the artcileInterfacial characteristics of barite, calcite, and scheelite in aqueous solution, and their flotation, Category: catalysis-chemistry, the publication is Nippon Kogyo Kaishi (1981), 97(1118), 251-6, database is CAplus.
A surface chem. study was made on the floatability of barite??[13462-86-7] and calcite??[13397-26-7] and scheelite??[14913-80-5] with dodecyl?ammonium?acetate (DAA) [2016-56-0] and sodium?dodecyl?sulfate (SDS) [151-21-3]. Floatability of barite changed when pH deviated from the equivalence point, EP (pH = 7.6), due to the surface hydrolysis. EP compared well with the isoelec. point. Barite was well floated with SDS, irresp. of pH, because of the chem. adsorption of SDS. The flotation of calcite changed considerably with pH, due to the change in the concentration of chem. species in the aqueous phase with pH.
