product of mineral extraction in underground mines. The quantity and composition of waste rock varies greatly from site to site, but these wastes essentially contain the minerals associated with both the ore and host rock. The ratio of overburden excavated to the amount of mineral removed is called the overburden ratio or stripping ratio. For example a stripping ratio of 4:1 means that 4 tonnes of waste rockMine Waste Transfer and Disposal Methods - Mine Tailings,,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.

These may include traces of aluminum,Easy Guide to Mining Waste Characterisation - EESI Group,Waste Rock Characterisation. Ore is divided into oxidised (above the water table); transitional (within the zone occasional inundated by groundwater); and primary (below the water table at all times). This is usually defined by geologists, as it impacts on metallurgy. Waste rock associated with mining ore for precious and base metals, coal, mineral sands and certain gems is often associated,
