    Mill tailings are the fine-grained, sandy waste byproduct material that remains after the milling process has extracted and concentrated the uranium from the ore. Mill tailings are typically created in slurry form during processing, and are then deposited in an impoundment or "mill tailings pile," which must be carefully regulated, monitored

      Mine tailings typically consist of process effluent and finely-ground rock generated at the mine processing plant. Tailings have no financial gain to a mine or mineral operator and as such, tailings are usually stored in the most cost-effective way possible to meet site specific factors as well as adhere to relevant environmental regulations.
