Open-pit mining methods are applicable to mining ore deposits that apex at or near the surface. If the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of open-pit mining. The removal of this material is known as stripping. The stripping-pit limits must be extended beyond the limits of the ore pit to provide a bench, and the pit

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
The definition of a open pit mine is "an excavation or cut made at the surface of the ground for the purpose of extracting ore and which is open to the surface for the duration of the mine’s life." To expose and mine the ore, it is generally necessary to excavate and relocate large quantities of waste rock.
Mar 24, 2017· Thus, the lower the operating costs, the lower the grade of ore that can be mined. An open pit requires large equipment used to mine large quantities of ore
furnace. The use of sintered ore should also result in lower furnace maintenance costs and increased furnace availability. (Van Antwerpen 2004.) (Figure 4.)
