Open pit mining, also known as strip mining, is the removal of surficial soils and uneconomic rock to get at the ore below. Ore grades are normally less than %. This is type of mining is only possible if the uranium ore is near the surface (normally less than 400 ft).
The mining process is unique in that unlike most industrial processes, the starting raw materials and conditions for production vary widely, sometimes by more than an order of magnitude, in energy intensity (Btu/ton produced).
A coal preparation plant is a facility that washes coal of soil and rock, crushes it into gradedCoal needs to be stored at various stages of the preparation process, and conveyed around the CPP reduces the overall topsize of the ROM coal so that it can be more easily handled and processed within the
"pit or tunnel in the earth for obtaining metals and minerals,", from Old French mine "vein, lode; tunnel, shaft; mineral ore; mine" (for coal, tin, etc,), of uncertain origin, probably from a Celtic source (cf.
