Retreatment of gold residues - ScienceDirect

Jan 01, 2005 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

Where have all the mine dumps gone? | The Heritage Portal

Apr 06, 2017 The early methods of gold extraction would send the tailings (discard) to sand dumps, but as time went by improved methods of extraction would create a slime that could be disposed of by pumping to a slimes dam.
