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 reverse flotation, which method comprises the step of (c) adding a compound of formula I wherein Ris C-Calkyl or alkenyl, which is linear or branched, Ris H, C-Calkyl, which is linear or branched, Ris —X—NH, H or C-Calkyl, which is linear or branched, and X is C-Calkylene, which is linear or branched, or a salt of a protonated compound of formula I and an anion, to a prepared aqueous pulp of the ore and optionally one or more flotation auxiliaries to obtain an aqueous mixture. Furthermore, a method for manufacturing a specific group of compounds of formula I, i.e. compounds of formula 1-X wherein Ris C-Calkyl, which is linear or branched, Ris H, Ris —X—NHand X is C-Calkylene, which is linear or branched, is disclosed.

Method for flotation of a silicate-containing iron ore with a cationic collector

The present invention relates to the use of hydrophobically associative copolymers as binders for pelletizing metal containing ores such as iron containing ores. The copolymers comprise monomer units derived from at least one hydrophobically as sociative monomer, preferably at least one unsaturated hydrophobically associating monomer.
