Usui, Shinnosuke published the artcileThe effect of grade of quartz on the cationic flotation of quartz from hematite, Recommanded Product: Dodecylamineacetate, the publication is Tohoku Daigaku Senko Seiren Kenkyusho Iho (1980), 36(1), 17-22, database is CAplus.
Flotation experiments were carried out with quartz [14808-60-7] and hematite [1317-60-8] (44-53 ¦Ì), sep. and mixed, using a Denver-type laboratory floatator, at various values of pH and collector (dodecyl ammonium acetate DAA [2016-56-0]) concentration, with special reference to the effect of the grade of quartz on the reverse flotation of quartz. The individual flotation indicated that complete flotation of quartz was obtained at a DAA concentration of (5 ¡Á 10-5)-(1 ¡Á 10-4)M (0.25-0.5 kg/ton) and at pH 5-5.4, midpoint of isoelec. points of resp. minerals, while no flotation of hematite took place under corresponding conditions. In the flotation of the mixed sample an incomplete separation was obtained under the same conditions; the floatability of quartz decreased while that of hematite increased. The floatability of quartz decreased with decrease in grade, indicating that the reverse flotation of low-grade quartz from hematite becomes difficult. The poor separation of quartz described above was improved considerably by the addition of 1 ¡Á 10-4M sodium gluconate [527-07-1].
