More Information
Summary: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.
