Collector compositions and methods of using the same

摘要

Formulations for value mineral collector compositions composed of at least one first collector selected from an organic ammonium salt of an organic sulfur-containing acid; and at least one second collector selected from neutral collectors and/or organic ammonium salts of an organic sulfur-containing acids, such that the second collector is different from said first collector, are provided herein, along with methods for making and using same.

1. A collector composition comprising:
a) one or more of a first collector comprising an organic primary, secondary, tertiary, or quaternary ammonium salt of an organic sulfur-containing acid, wherein said organic sulfur-containing acid is selected from the group consisting of hydrocarbyl dithiophosphoric acids, hydrocarbyl monothiophosphoric acids, mercaptobenzothiazoles, hydrocarbyl xanthic acids, hydrocarbyl dithiocarbamic acids, hydrocarbyl thioglycolic acids, hydrocarbyl trithiocarbonic acids, hydrocarbyl dithiophosphinic acids and hydrocarbyl monothiophosphinic acids; and b) at least one second collector selected from the group consisting of neutral collectors and organic ammonium salts of organic sulfur-containing acids, wherein the organic ammonium salts of sulfur-containing acids of the second collector are different from said organic ammonium salts of sulfur-containing acids of the first collector, with the proviso that when the first collector comprises a primary or secondary ammonium salt of an organic sulfur-containing acid and the second collector is a neutral collector, the neutral collector is selected from the group consisting of dihydrocarbyl thionocarbamates, dihydrocarbyl thioureas, dihydrocarbyl sulfides, trihydrocarbyl dithiocarbamates, N-hydrocarbyl-S-hydrocarbyl dithiocarbamates, dihydrocarbyl guanidines, S-hydrocarbyl dithiophosphinates, S-hydrocarbyl dithiophosphates, S-hydrocarbyl mercaptobenzothiazoles, O-hydrocarbyl monothiophosphates, and O-hydrocarbyl monothiophosphinates.
