Beschreibung
Zusammenfassung:	The present invention provides a ammoniated collector (amine, azepine, etc.) alone or in combination with other thiol-type collecting reactants, as well as sodium, iron, magnesium, and/or manganese sulfates, sulfurs, oxides, and hydroxides, acrylic acid polymers and copolymers or other spreading agents, in the process of grinding and floatin g mineral ores, in order to allow to set new floating operational conditions in existing minera l ore processing plants; to obtain substantial improvements in metallurgic productivity by improving the kinetics of the floating process, which allows to increase recovery of molybdenum, decrease recovery of iron, increase copper grade in copper concentrate, at least keep or improve copper recovery, among others, through the addition of a collecting reactant implyi ng savings of up to 100% of consumption of modifying agents, such as lime, currently use d.
