Abstract (en)
[origin: CA2083818A1] D 9130 A process for the recovery of minerals from non-sulfidic ores by flotation Esters of dicarboxylic acids with fatty acid monoalkanolamides, optionally in admixture with other anionic or nonionic surfactants, are suitable as collectors for the flotation of non-sulfidic ores, more particularly apatite.
Abstract (fr)
Des esters d'acides dicarboxyliques avec des monoalcanolamides d'acides gras, le cas échéant mélangés à d'autres agents tensio-actifs anioniques ou non ioniques, sont utiles comme collecteurs lors de la flottation de minerais non sulfurés, notamment l'apatite.
