  • Lecture 4: Mining waste SGU

    Waste RockTailingsMine WaterChemicals Used in ProcessingWaste rock is the rock that is excavated to reach the ore. The amount of waste rock that needs to be removed depends on the geometry and location of the ore body, along with the mining method used and the composition and stability of the rocks. The ratio between waste rock and ore production is called the stripping ratio. For example, a stripping ratio of 2:1 means that 2 tonnes of waste rock needs to be mined to mine 1 tonne of ore.
