Polishing Pond Modification - Hudbay Minerals, Reed Copper Project
March completed preliminary design options for cleaning out settled and suspended solids in a polishing pond while it was in operation. The continuous flow entering the pond was unable to be shut down because of underground mining and groundwater control. March presented three options to Reed that would enable cleaning out the pond while meeting all MMER requirements and specifications. Solids removed from the pond were to be placed in the TMF area. Therefore, minimal fluids were allowed to be removed with the solids. This eliminated the need for any fluids to be contained and treated.
