Mining Collectors
A family of mining collectors and surfactants that uses alkoxylates allows for the easy adjustment of solubility and molecular weight useful because anionic and cationic mineral collectors require such varying degrees of solubility and molecular weight. The family of the present invention allows for the optimization of both parameters and an increase in collector efficiency.
Method For Flotation Of A Phosphate-Containing Ore
The invention relates to a method for manufacturing a concentrate enriched in a phosphate mineral content from an ore, which contains a phosphate mineral and a non-phosphate mineral, by a flotation, which method comprises the step of adding a surfactant system comprising (A) a fatty acid, (B) a blend of ethoxylated and non-ethoxylated alcohols, which is obtainable by blending (i) a reaction product of a first C.sub.12-C.sub.16 aliphatic alcohol having an average degree of branching of 1.9 to 3.5 and 10 to 20 equivalents of ethylene oxide, and (ii) a second C.sub.12-C.sub.16 aliphatic alcohol having an average degree of branching of 1.9 to 3.5, wherein the amount of (i) is 80 to 95 wt. % and the amount of (ii) is 5 to 20 wt. % and wt. % is based on the overall weight of the mixture of ethoxylated and non-ethoxylated alcohols, to a prepared aqueous pulp of the ore and optionally one or more flotation auxiliaries to obtain an aqueous mixture. Furthermore, a use of the surfactant system as flotation collector is disclosed.
NEW FROTHERS FOR MINERALS RECOVERY AND METHODS OF MAKING AND USING SAME

Process for manufacturing white pigment containing products
The present invention concerns a process for manufacturing white pigment containing products. The white pigment containing products are obtained from at least one white pigment and impurities containing material via froth flotation.
COLLECTOR COMPOSITION
Presently claimed invention is directed to a collector composition for the beneficiation of a mineral comprising at least one component (A) selected from the group consisting of anionic (A1) surfactants, cationic (A2) surfactants, ampholytic (A3) surfactants and non-ionic surfactants (A4), and at least one component (B) selected from the group consisting of alkoxylated polyalkyleneimine (B1) and alkoxylated hexamethylene diamine (B2).
Concentration process of iron ore slimes
The present application relates to a concentration process of iron minerals from ultrafine tailings (slimes) from iron ore processing through reverse flotation with pH between 8.5 and 10.5 with the addition of amide-amine type collector, or further a mixture thereof with traditional cationic collectors (amines), in the absence of any depressant, alternatively including a step of high field magnetic concentration, which allows to obtain a concentrate with iron content higher than 66% and contents of SiO2+Al2O3 below 4%.
COLLECTORS FOR FLOTATION PROCESS
The present invention relates to the flotation of non-sulfidic minerals and ores. Particularly the present invention relates to a collector for the beneficiation of non-sulfidic minerals and ores.
COLLECTOR COMPOSITIONS CONTAINING A N-ACYLATED AMINO ACID AND PROCESS TO TREAT NON-SULFIDIC ORES
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.
MIXTURE OF OCTENE HYDROFORMYLATION BY-PRODUCT AND DIESEL, KEROSENE OR C8-C20 OLEFINS AS COLLECTORS
