Abstract
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.

A composition, comprising a polyamidoamine having the chemical formula:
- wherein:
- R1 and R2 are different and selected from a saturated or unsaturated, substituted or unsubstituted, linear or branched, cyclic, heterocyclic, or aromatic hydrocarbyl group,
- R3 and R4 are independently hydrogen or a saturated or unsaturated, substituted or unsubstituted, linear or branched, cyclic, heterocyclic, or aromatic hydrocarbyl group,
- each m is an integer of 1 to 5, and
- n is an integer of 2 to 8.
An aqueous mixture, comprising:
- an ore;
- water;
- and
- a polyamidoamine having the chemical formula:
- wherein:
- R1 and R2 are different and selected from a saturated or unsaturated, substituted or unsubstituted, linear or branched, cyclic, heterocyclic, or aromatic hydrocarbyl group,
- R3 and R4 are independently hydrogen or a saturated or unsaturated, substituted or unsubstituted, linear or branched, cyclic, heterocyclic, or aromatic hydrocarbyl group,
- each m is an integer of 1 to 5, and
- n is an integer of 2 to 8.
A method for purifying an ore, comprising:
- combining an ore, water, and a polyamidoamine to produce an aqueous mixture, wherein the ore comprises an impurity, and wherein the polyamidoamine has the chemical formula:
- wherein:
- R1 and R2 are different and selected from a saturated or unsaturated, substituted or unsubstituted, linear or branched, cyclic, heterocyclic, or aromatic hydrocarbyl group,
- R3 and R4 are independently hydrogen or a saturated or unsaturated, substituted or unsubstituted, linear or branched, cyclic, heterocyclic, or aromatic hydrocarbyl group,
- each m is an integer of 1 to 5, and
- n is an integer of 2 to 8;
- collecting a flocculated material comprising the impurity and the polyamidoamine from the aqueous mixture;
- and
- collecting a purified ore having a reduced concentration of the impurity relative to the ore from the aqueous mixture.
