| titleOfInvention | ESTERQUATES FOR FLOTATION OF NON-SULFIDE MINERALS AND ORE AND METHOD |
| abstract | The invention relates to esterquats which can be obtained by reacting di- or trialkanolamines with a mixture of fatty acids and polycarboxylic acids and quaternizing the esters thus obtained with an alkylating agent, wherein said di- or trialkanolamines have formula (I) in which R1 and R2 independently of each other are hydroxyalkyl radicals containing 1-20 carbon atoms, hydroxyalkenyl radicals containing 2-20 carbon atoms and 1, 2 or 3 double bonds, or adducts of 1-20 mol of ethylene oxide with a hydroxyethyl group, and R3 is a hydrogen atom, an alkyl group containing 1-20 carbon atoms, alkenyl group containing 2-20 carbon atoms and 1, 2 or 3 double bonds, hydroxyalkyl group containing 1-20 carbon atoms, hydroxyalkenyl group containing 2-20 carbon atoms and 1, 2 or 3 double bonds, or adducts of 1-20 mol of ethylene oxide with a hydroxyethyl group; fatty acids have the formula (II), in which R4 is an aliphatic, linear or branched hydrocarbon group containing 5-29 carbon atoms and 0, 1, 2 or 3 double bonds; and polycarboxylic acids have the formula (III) in which Y is a carbon atom or a saturated or unsaturated aliphatic hydrocarbon group containing 2-5 carbon atoms, which optionally contains one or more hydroxyl groups, and X is a hydrogen atom or hydroxyl or carboxyl acid group. The present invention also relates to the use of said esterquats as collectors in the flotation of non-sulfide minerals. |
