  • Patent number: 12168237
    Abstract: The present disclosure relates to a collector composition containing (i) as a primary collector the compound of the formula (I) wherein R is an alkyl group containing between about 5 and about 16 carbon atoms that may be branched or linear, k is a value of about 1 to 3, m is an integer from about 0 to about 25, each A independently is —CH2-CH2- or —CH2CH(CH3)- or —CH2-CH(CH2-CH3)-, n is an integer of at least about 3 and at most about 8, and wherein X is an anion derivable from deprotonating a Brønsted-Lowry acid, and (ii) a second compound selected from the group of other primary collectors, secondary collectors, depressants, frothers, and solvents. The disclosure also relates to a process to treat siliceous ore that contains a step of froth flotating in the presence of a collector composition that contains the primary collector compound.

  • Patent number: 11629117
    Abstract: The present disclosure relates to a process to prepare esters of an amino carboxylic acid of the formula (I) comprising the steps of reacting an aminocarboxylic acid present as a cyclic amide of the formula II and an alkanol of the formula R—(O-A)mOH in the presence of the Brønsted-Lowry acid at a temperature of between 60 and 200 degrees C. wherein the total molar amount of aminocarboxylic acid to the molar amount of the alkanol is between 1:0.8 and 1:1.5 and wherein the Brønsted-Lowry acid is not added to the reaction mixture until least 50% of the total of the alkanol and cyclic amide are added to the reaction mixture.

  • Publication number: 20220176386
    Abstract: A collector composition suitable for treating non-sulfidic ores comprises (i) from about 1 to 50 wt % of an N acylated amino acid or salt thereof of the structural formula R1-CO—NX—CYH—(CH2)m-COOM (ii) from about 10 to 80 wt % of an alcohol alkoxylate of the formula R2-(AO)n wherein R1 is an alkyl or alkenyl group of 7 to 21 carbon atoms, X is a hydrogen atom or methyl group, Y is a hydrogen atom, a C1-C4 alkyl, a C1-C4 hydroxylalkyl, a C1-C4 carboxyalkyl, or a C1-C4 aminoalkyl group, m is 0 or 1, M is a proton, an alkalimetal cation, or a quaternary ammonium cation, R2 is an alkyl group of 6 to 20 carbon atoms, each AO is independently ethyleneoxy or propyleneoxy, provided that at least part of AO is ethyleneoxy, and n is higher than 2 and up to 25, the wt % based on the total weight of the composition.

  • Publication number: 20210198182
    Abstract: A process to prepare an amine-functional ester of an amino carboxylic acid includes the step of reacting a polyol of the formula (I) HO-A-OH??(I) where A is a carbon chain with about 2 to about 36 carbon atoms that is aliphatic linear or branched, saturated or unsaturated, or aromatic, or CH2CH(OH)CH2, CH2C(CH2OH)2CH2, CH2C(CH2OH)(CH3)CH2, CH2C(CH2OH)(CH2CH3)CH2, p-tetrahydrofuran, erythritol or an ester of di- or tricarboxylic acids with ethylene or propylene glycol, and wherein A can optionally be alkoxylated or reacted with hydroxy carboxylic acids, with an aminocarboxylic acid of formula II or its cyclic amide of the formula III, where m is an integer of about 1 to about 8 in formula II and about 3 to about 8 in formula III, each R independently is hydrogen or a C1-C4 alkyl group, or CH2CH2COOH, or CH2COOH, or (CH2)4NH2, in the presence of a Brønsted-Lowry acid.
