Overburden Wikipedia

In mining, overburden (also called waste or spoil) is the material that lies above an area that lends itself to economical exploitation, such as the rock, soil, and ecosystem that lies above a coal seam or ore body. Overburden is distinct from tailings, the material that remains after economically valuable components have been extracted from the generally finely milled ore. Overburden is removed during surface mining, but is typically not contaminated with toxic components. Overburden may also be used to restore an ex

‘overburden’ or ‘waste rock’) that must be moved or excavated to allow access to the metallic ore deposit. For most mining projects, the quantity of overburden generated by mining is enormous. The ratio of the quantity of overburden to the quantity of mineral ore (called the ‘strip ratio’) is usually greater than one, and can be much

Other than pipe-shaped bodies, most small-scale gold deposits have a linear component.

Stripping ratio Wikipedia

In mining, stripping ratio or strip ratio refers to the ratio of the volume of overburden (or waste material) required to be handled in order to extract some tonnage of ore.For example, a 3:1 stripping ratio means that mining one tonne of ore will require mining three tonnes of waste rock. Stripping ratios are typically reduced to show the volume of waste removal required to extract one unit
