The present invention relates to the use for ore beneficiation, of at least one derivative of alkoxylated (polyester)amine. The present invention also relates to the flotation pulp and the tailings comprising said product useful for ore beneficiation.

Use of alkoxylated amines as collector agents for ore beneficiation

Provided is a method of beneficiating an ore including contacting an ore with a compound represented by formula (1): where the structural variables are defined herein.

The present invention relates to a method for preparing 1-(2-aminoethyl)imidazolidin-2-one or the thiocarbonyl thereof, and also to the product that can be obtained according to this method, and which has a purity of at least 98%, and to the uses thereof.

Method for preparing and using aminoethyl imidazolidinone and the thiocarbonyl thereof

Method for preparing aminoethyl imidazolidinone or the thiocarbonyl thereof

Aqueous-alcoholic solutions of hydrogenated coconut or palm kernel oil alkylamidopropylbetaines with a betaine content of greater than 50%, which are fluid, stable and pumpable are described as occupying a well-defined zone of their betaine/water/ethanol ternary diagram. They are prepared by synthesis and quaternization of the amidoamine directly in the solvent medium in which they are defined.
