<p>Disclosed herein are systems and methods for recovering a target material from an aqueous stream. The target material can be a natively hydrophobic target material, such as a hydrocarbon material, such as coal. The target material can also have a surface modification that renders it hydrophobic. Systems for recovering the target material can comprise an extractant formulation comprising a light hydrocarbon solvent and a high molecular weight hydrophobic polymer, wherein the extractant formulation is mixable with the aqueous stream in a mixer to form an admixed solution having a hydrophobic portion and an aqueous portion, with the target material partitioning to the hydrophobic portion; a separator for isolating the hydrophobic portion from the aqueous portion; and a collector to which the hydrophobic portion is directed, wherein the target material is recovered from the hydrophobic portion.</p> |
