    摘要: An emulsion comprising polymers and method for making same is provided. The polymers consist of the following monomers: (a) 20 to 55% by weight acrylic and/or methacrylic acid; (b) 40 to 80% by weight C1-C4 alkyl (meth)acrylates; (c) 1 to 40% by weight of a maleic acid ester according to general formula (I) R2OOC—CH═CH—COO(CH2CH2O)nR1  (I) wherein R1 represents a linear or branched alkyl, aryl or alkaryl radical having 8 to 22 carbon atoms, R2 represents hydrogen or (CH2CH2O)nR1 and n represents a number between 2 and 150, (d) 0 to 15% by weight of aralphatic compounds having at least one double bond in the aliphatic side chain; and (e) 0 to 1% by weight polyethylenic unsaturated cross-linking monomers, wherein the amounts of components (a) to (e) total 100% by weight.

    摘要: A process for the flotation of non-sulfidic minerals or ores, is disclosed in which crushed crude minerals or ores are mixed with water and a collector to form a suspension, air is introduced into the suspension in the presence of a reagent system, and a floated foam containing the non-sulfidic mineral or ores is formed therein along with a flotation residue comprising the gangue polymeric esterquats as the collector polymeric esterquats. The polymeric esterquats are obtained by reacting alkanolamines with a mixture of monocarboxylic acids and dicarboxylic acids and quaternizing the resulting esters, optionally after alkoxylation.
