CATIONIC COLLECTORS WITH MIXED POLYAMIDOAMINES AND METHODS FOR MAKING AND USING SAME

摘要

Compositions that include a polyamidoamine, aqueous mixtures that include the polamidoamine and an ore, and methods for making and using same. The composition can include a polyamidoamine having the chemical formula (A). In the chemical formula (A), R1 and R2 can be different and can be selected from a saturated or unsaturated, substituted or unsubstituted, linear or branched, cyclic, heterocyclic, or aromatic hydrocarbyl group, R3 and R4 can independently be hydrogen or a saturated or unsaturated, substituted or unsubstituted, linear or branched, cyclic, heterocyclic, or aromatic hydrocarbyl group, each m can be an integer of 1 to 5, and n can be an integer of 2 to 8. The aqueous mixture can include an ore, water, and the composition.
