Open pit mining results in two waste streams: waste rock which contains no economic quantity of minerals but which must be removed to gain access to the orebody, and tailings which are the result of a mineral separation process in the concentrator or processing plant. The mining rate includes the mining of both waste and ore.

Mining has been a part of the Earth’s history since prehistoric times. Mining has played a role throughout the millennia – from Neanderthals’ use of stone, to ancient Egyptians’, Greeks’, Romans’ and Incans’ more sophisticated mining processes and uses of mined materials.
