Research on the

uncontrolled release of acid mine drainage as a result of poor management of tailings dams (or slimes dams), sand and waste rock dumps, is the single most important impact mining has on the environment (Ferguson & Erickson, 1988). In general, mine residues consist of high volume, low toxicity wastes according to the United States

Retreatment of gold residues

Gold-mining residues typically fall into one of three categories comprising slime (particle size of about 75% passing 74 μm), sand (about 10–20% passing 74 μm) and waste rock.Since the slime and sand has been previously processed, it typically has a low gold grade (<1.0 g/t) and will provide relatively low recovery efficiencies, in the order of 50%.
