The present invention relates to a collector composition containing 80 to 100 wt % of at least one alkylethermonoamine, less than 20 wt % alkyletherdiamine, all wt % based on total weight of all amine components, and wherein the alkylethermonoamine contains between 60 and 93% isotridecyl(C13)etherpropylamine, 5 and 30% of isododecyl(C12)etherpropylamine, 0 and 10% of isoundecyl(C11)-etherpropylamine, 0 and 10% of isodecyl(C10)etherpropylamine, 2 and 10% tetradecyl(C14) etherpropylamine, all % being based on total weight of alkylethermonoamine and the use thereof in a process to treat iron ore.

Process to treat magnetite ore and collector composition

The application relates to compositions comprising di-fatty-alkyl or -alkenyl polyalkylamines of the general formula (I) or (II), to a process for their preparation which involves a cyanoethylation step and a hydrogenation step, and their use as demulsifiers for oil-in-water emulsions, corrosion inhibitor, fuel additive, anti-scaling agent, asphalt additive, enhanced oil recovery agent for oil-wells, cutting-oil additive, and anti-static agent. The product show good performance combined with a favourable viscosity profile.
