Mine Waste Transfer and Disposal Methods - Mine Tailings
Overburden -> Gangue -> Tailings. Overburden Waste rock, or overburden, refers to the often large mass of initial soil and rock that is removed in order to get to the valuable mineral deposits in mining operations. Typically, for every ton of ore that is mined, 5 tons of overburden must be displaced.
