Equipment Selection for Surface Mining: A Review
A surface mine contains pits with mineral endowed rock (or ore). We extract ore that lies within the upper layer of the earth, from surface mines (Fricke, 2006) . This ore can include metals such as iron, copper, coal and gold. There are several methods of surface mining, including openpit, stripping, dredging and mountaintop removal.

Open pit copper mining MAXAM
Openpit mining is used when the orebodies are extensive and relatively close to the surface. The sterile/ore ratio is one of the factors which defines the exploitation method and the final dimensions of the mine cuts. In general, openpit mining consists of a system to exploit open pits with multiple benches.

An Introduction To Surface Mining
Openpit mining is usually utilized for nearsurface deposits, such as gravel and sand. The term "quarry" often refers to an openpit mine, where the product is rock (commonly building stone) usually either gravel, sand, or dimension stone. Openpit mining is relatively safe and cheap, and it also yields more final products.

Environmental Risks of Mining
Open pit mining. Open pit mining, where material is excavated from an open pit, is one of the most common forms of mining for strategic minerals. This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined.
