  • Open-pit mining, also known as opencast mining, is a surface mining technique that extracts minerals from an open pit in the ground.
  • It is the most common method used worldwide for mineral mining and does not require extractive methods or
  • It is an appropriate extraction method when mineral or ore deposits are found relatively close to the earth’s surface, which is overlain by relatively thin vegetation, topsoil, and rock (collectively called overburden).
  • It uses a series of level surfaces or benches to reach the deposit, forming an open pit that looks similar to an inverted pyramid.
  • Open-pit mines undergo constant expansion until all mineral resources are exhausted.
  • Most of the world’s annual output of copper, gold, and iron ore is from open-pit mining
  • Other commodities produced from open-pit mining include diamonds, molybdenum, manganese, lead and zinc, uranium, and a variety of industrial minerals, such as borates, talc , etc.
  • Open-pit mining has higher productivity, lower operating costs, and is relatively safer than other mining methods.
