Usui, Shinnosuke published the artcileSeparation of quartz and hematite by reverse flotation using dodecylamine. I. Effect of particle size on reverse flotation of quartz from hematite using dodecylamine in acidic media, SDS of cas: 2016-56-0, the publication is Nippon Kogyo Kaishi (1983), 99(1148), 915-20, database is CAplus.
Separation by reverse flotation of a mixture of powd. quartz and hematite was carried out in the presence of docecylamine?acetate??[2016-56-0] in acidic solution of pH 5, where quartz is neg. and hematite is pos. charged. The separation was complete except when hematite particle size was 10¦Ì, owing to coagulation of quartz and hematite or slime coating of hematite on quartz. A critical particle size of hematite likely to cause the slime coating was 0.3¦Ì.
Nippon Kogyo Kaishi published new progress about 2016-56-0. 2016-56-0 belongs to catalysis-chemistry, auxiliary class Active Esterification, name is Dodecylamineacetate, and the molecular formula is C14H10O4, SDS of cas: 2016-56-0.
