What is the difference between the geography of enterprises producing ferrous, heavy and light non-ferrous metals?

Enterprises that produce ferrous metals (for example, steel, cast iron, iron) are most often located in areas where iron ores originate and in an area that is rich in forests. Producers of heavy metals (for example: nickel, tin) are located near the areas where they are mined, since the ores have a low metal content. Enterprises for the production of light non-ferrous metals (for example: magnesium, titanium) are located near sources of inexpensive electrical energy or near a hydroelectric power station (hydroelectric power station).
