Abstract: The present disclosure includes embodiments of a recirculation system and methods for mitigating release of silica dust at a hydrocarbon well site. The embodiments of the recirculation system may include a blender hopper, one or more proppant silos, a footed hood, a conveyor, one or more amplifiers, one or more compressed air sources, one or more vacuum hoses, an augur, and a blender. In one or more embodiments, the methods of recirculating silica dust to mitigate the release of silica dust includes conveying sand proppant on a conveyor from the one or more proppant silos to a blender hopper, directing sand proppant from the conveyor into the blender hopper, supplying compressed air to one or more amplifiers, directing sand proppant from the blender hopper to a blender via an augur, and adjusting the extent of at least one of the two or more leg segments and the leg adjustment arrangement.
