Open-pit mining, also known as open-cast or open cut mining, is a surface mining technique of extracting rock or minerals from the earth by their removal from an open-air pit, sometimes known as a borrow. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining. Open-pit mines are used when deposits of commercially useful ore or rocks are

Coal is mined either by surface methods (open-cut or open-cast mining) or by underground techniques. In surface mining, all of the rock from the ground surface to the top of the seam (material referred to as overburden) is removed and set aside to expose the coal, which is then taken out and transported from the mine for preparation and use ( Figure 11 ).
12-01-2021 Geita is a multiple open-pit operation with underground potential, which is currently serviced by a 6Mtpa carbon-in-leach (CIL) processing plant. Standard open-pit mining methods are employed: hard overburden is drilled and blasted, hydraulic excavators are used to load waste material into a fleet of 100t dump trucks exposing the gold-bearing ore material which is directed to the processing plant.
This arrangement and flowsheet of a Mini Portable Gold Processing Plant permits several mineral separations by flotation and provides for the possible recovery of other minerals by gravity concentration. The flowsheet is ideal for a pilot-plant in field testing of ores to determine the economic feasibility of an ore deposit prior to the installation of a larger plant or for processing ore ...

Mining at Martha is by open pit methods. Ore and waste rock are crushed at the surface facilities area prior to transportation along a 2.7 kilometre conveyor. On arrival at the processing plant gold and silver are extracted from the ore using conventional carbon-in-pulp treatment methods.
Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.
Hidden Valley is an open-pit, gold-silver mine and processing plant in Morobe Province. The mine is approximately 210 km north-north-west of Port Moresby , and 90 km south-southwest of Lae .

The company would require $500m over a decade to buy the mine, equip and operate it and build a $50m processing plant. "We will be spending approximately $50m a year at the operation, but we'll be generating in excess of 60,000 ounces of gold." With the gold price at around $2000 an ounce, the mine would earn about $120m a year.

1.1.3.1 Open-pit mining Open-pit mining is a type of strip mining in which the ore deposit extends very deep in the ground, necessitating the removal of layer upon layer of overburden and ore. In many cases, logging of trees and clear-cutting or burning of vegetation above the ore deposit may precede removal of the overburden. The
