The invention is directed to systems and methods of removing particulate matter from a fluid, comprising: pre-activating the particulate matter to form a pre-activated particulate matter; providing an activating material capable of being affixed to the pre-activated particulate matter; affixing the activating material to the pre-activated particulate matter to form an activated particle; providing an anchor particle and providing a tethering material capable of being affixed to the anchoring particle; and attaching the tethering material to the anchor particle and the activated particle to form a removable complex in the fluid that comprises the particulate matter, wherein the particulate matter is derived from a mining operation.

Systems and methods for removing finely dispersed particles from mining wastewater

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.

Recovering valuable mined materials from aqueous wastes

Disclosed herein are systems for removing particulate matter from a fluid, comprising a particle functionalized by attachment of at least one activating group or amine functional group, wherein the modified particle complexes with the particulate matter within the fluid to form a removable complex therein. The particulate matter has preferably been contacted, complexed or reacted with a tethering agent. The system is particularly advantageous to removing particulate matter from a fluid waste stream following mining or ore processing operations.

Systems and methods for removing finely dispersed particulate matter from a fluid stream

Systems and methods are presented for removing an ionic material from a fluid using a capture polymer that sequesters the ionic material and an anchor particle bearing a tethering polymer. The tethering polymer complexes with the capture polymer after the capture polymer has sequestered the ionic material, thereby affixing a complex of capture polymer and ionic material to the anchor particle to form a removable complex. The removable material can be segregated from the fluid via a removal system, thereby removing the ionic material from the fluid.

Method for removal of dissolved metal cations from aqueous fluids using modified capture polymers and tether polymer bearing anchor particles

The present invention provides compositions, systems and methods for using coal from coal processing sources to remove coal fines from a mixture and form a coal-on-coal composite particle.
