Abstract
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.
