Abstract

L'invention concerne l'utilisation de "composés quaternaires d'esters" comme adjuvants pour la flottation de minerais non sulfurés. Il a été découvert que les produits d'estérification quaternarisés des mono, di ou trialcanolamines contenant des acides carboxyliques aliphatiques, dénommés composés quaternaires d'esters, présentent d'une part de bonnes propriétés collectrices, notamment pour la flottation des silicates, et d'autre part, tant en aérobiose qu'en anaérobiose, une remarquable biodégradabilité.
