Beschreibung
Zusammenfassung:	The present invention relates to a compound obtainable by the condensation of a polyol having 3-4 hydroxyl groups, adicarboxylic acid or a derivative thereof, an alkanolamine anda fatty acid, followed by reaction with an alkylating agent. This compound is useful as a collector in a process for the reverse froth flotation of non-sulfidic ores containing silicate as impurities, especially phosphate ores. La présente invention concerne un composé pouvant être obtenu par la condensation d'un polyol ayant 3 à 4 groupes hydroxyle, d'un acide adicarboxylique ou d'un dérivé de ce dernier, d'une alcanolamine et d'un acide gras, suivie d'une réaction avec un agent alkylant. Ce composé est utile comme collecteur dans un procédé pour la flottation par mousse inverse de minerais non sulfurés contenant du silicate comme impuretés, en particulier de minerais de phosphate.
