Horioka, Masakazu published the artcileStudy on the refining of natural zeolite by adsorbing particle flotation, Application of Dodecylamineacetate, the publication is Yamagata-ken Eisei Kenkyushoho (1982), 9-15, database is CAplus.
The floatabilities of natural zeolite, quartz feldspar, 1:1 mixture of natural zeolite-quartz, and 1:1 mixture of natural zeolite-feldspar were investigated by the Denver-type laboratory flotation machine using dodecylammonium acetate (I) and pine oil as a collector. The Cs adsorption capacity of zeolite recovered by I flotation in the acidic state < pH 2, was less than that of the natural zeolite. However, the capacity was improved when treated with 1N NaOH or 1N KCl. Quartz and feldspar were separated from natural zeolite by I flotation in a HCl or H2SO4 circuit at pH 0.5-2, but not in neutral or alk. pH range. The selective separation of zeolite from the mixture of natural zeolite-quartz or natural zeolite-feldspar was achieved by using I (100 mg/L) at pH 1.1 together with pine oil (46 mg/L) as a collector. The recovery and the content of zeolite as froth were about 83 and 77%, resp.
