Open Pit Mining IntechOpen
Open pit mining is defined as the method of extracting any near surface ore deposit using one or more horizontal benches to extract the ore while dumping overburden and tailings (waste) at a specified disposal site outside the final pit boundary. Open pit mining is used for the extraction of both metallic and nonmetallic ores.

Geology, Prospecting and Exploration for Iron Ore Deposits
The airborne magnetometer is the primary geological tool used in the search for iron ores and iron bearing materials in large areas. The method of conducting an airborne magnetic survey is to install a flux gate or proton precision magnetometer in an airplane which traverses the target area at a fixed altitude and along predetermined flight lines.

How do we extract minerals? | Geological Survey
Large tabularshaped ore bodies or ore bodies lying more than 1,000 feet (300 m) below the surface are generally mined underground as well. The rock is drilled and blasted, then moved to the surface by truck, belt conveyor, or elevator. Once at the surface, the material is sent to a mill to separate the ore from the waste rock.

Mines, Minerals, and "Green" Energy: A Reality Check Manhattan Institute
For example, building a single 100MW wind farm— never mind thousands of them—requires some 30,000 tons of iron ore and 50,000 tons of concrete, as well as 900 tons of nonrecyclable plastics for the huge blades. With solar hardware, the tonnage in cement, steel, and glass is 150% greater than for wind, for the same energy output.

Mild steel. Mild steel is iron containing up to about % of carbon. The presence of the carbon makes the steel stronger and harder than pure iron. The higher the percentage of carbon, the harder the steel becomes. Mild steel is used for lots of things nails, wire, car bodies, ship building, girders and bridges amongst others.
