More Information
Summary:The invention relates to a method for manufacturing a concentrate enriched in iron mineral content from an ore, which contains an iron mineral and silicate, by a reverse flotation, which method comprises the step of (c) adding a collector composition comprising(i) an amidoamine, which contains a compound of formula Ior a salt of a protonated compound of formula I and an anion;(ii) an ethoxylate, which contains a compound of formula IIRE-O-(-CH2-CH2-O-)n-H  (II),wherein RE is a linear or mono-branched aliphatic C10-C20 alkyl or a linear aliphatic C10-C20 alkenyl, and n is an integer from 1 to 12,to a prepared aqueous pulp of the ore and optionally one or more flotation auxiliary to obtain an aqueous mixture. Furthermore, the use of the collector composition as a flotation collector is described and the collector composition itself
