Strip Mining, Openpit Mining, Surface Mining, Mining
The steps in strip mining are similar to openpit mining. The steps are: The trees and bushes are pushed down through bulldozers. This waste, along with the filth or sand under it, is taken to a close area and dumped. When the coal or mineral is found, it may be broken up by the blazing. The size of the chunks is important because the

When it is economically feasible, a mine may extract both types of copper minerals; when it is not possible, mines will only process either the copper oxides or the copper sulfides. The first steps of copper processing are the same for both ores: mining and transporting. Copper mining is usually performed using openpit mining, in which a series of stepped benches are dug deeper and deeper

Openpit 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 openpit mining. The removal of this material is known as stripping. The strippingpit limits must be extended beyond the limits of the ore pit to provide a bench, and the pit
