Compositions, aqueous mixtures that include the composition and an ore, and methods for making and using same. The composition can include an organic acid and a polyamidoamine. The polyamidoamine can have the chemical formula (A). In the chemical formula (A), R 1 and R 2 can independently be a saturated or unsaturated, substituted or unsubstituted, linear or branched, cyclic, heterocyclic, or aromatic hydrocarbyl group, R 3 and R 4 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. |
