Modern mining

 · Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and final reclamation of the land after the mine is closed. Mining techniques can be divided into two common excavation types: surface mining and sub- surface (underground) mining.

Green Energy Reality Check: It''s Not as Clean as You Think ...

 · For example, building a single 100-MW 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.
