Many people "mine" old dumpsites for pure metals and other materials. There is, however, no source of pure aluminum in nature. Aluminum ore (Bauxite) is composed of aluminum oxids and hydroxides
no
Pure aluminium is expensive.
Yes, bauxite is the ore of aluminium (aluminum). It is normally found close to the surface so is strip or quarry mined.
pure aluminium is very soft and it is ductile (flexible)
Aluminium alloys are stronger than pure aluminium, which is comparatively soft. Pure aluminium is also considered chemically reactive (thus the layer of aluminium oxide which coats the metal due to oxidation). Pure aluminium hardly exists due to its strong affinity with oxygen in air. In fact, aluminium foils and beverage cans are also alloys of aluminium, with about 92 to 99% of aluminium. So likewise, bike frames are also made of alhminium alloys because of its characteristics of being strong and lightweight.

Is zachary Tovslovich a real person?

you can dig any rock out of the ground
Yes, cats can dig holes in the ground.
Aluminium is a pure substance
Pure copper hasn't aluminium.
