Mine Waste Transfer and Disposal Methods - Mine

Overburden. Waste rock or overburden refers to the often large mass of initial soil and rock that is removed to get to the valuable mineral deposits. Typically, for every ton of ore that is mined, 5 tons of overburden is displaced. Overburden is not subjected to any chemical processes but must be removed to access the ore underneath.

Chapter 4: Mining waste - SGU

The amount of waste rock that needs to be removed depends on the geometry and location of the ore body, mining method and the composition and stability of the bedrock. The ratio of waste rock/ore is called stripping ratio. For example, a stripping ratio of 2:1 means that 2 tonnes of waste rock needs to be removed to mine 1 tonne of ore.
