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

摘要

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 tailing solution.

1. A method of removing particulate matter from a fluid, comprising:
affixing an activating material to the particulate matter in the fluid to form an activated particle, wherein the activating material is an anionic partially hydrolyzed polyacrylamide; attaching a tethering material to an anchor particle to form a tether-bearing anchor particle, wherein the tethering material is a cationic polymer, adding the tether-bearing anchor particle to the fluid comprising the activated particle, wherein the tethering material attaches to the activating material forming a removable complex in the fluid, wherein the removable complex comprises the particulate matter and the anchor particle; and removing the removable complex from the fluid thereby removing the particulate matter from the fluid.
