What Exactly Are Mining Tailings? At its simplest, tailings are the leftover materials after the economically valuable minerals have been extracted from the ore. Imagine a bucket of dirt containing tiny flecks of gold. The mining process is essentially a very large-scale version of separating the gold from the rest of the dirt.
