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 floating mineral ores,
in order to allow to set new floating operational conditions in existing
mineral 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 implying savings of up to 100% of consumption of
modifying agents, such as lime, currently used.
