Ferrous alloys generally refer to iron-based alloys, or iron and steel. Since iron was discovered
and first used approximately three thousand years ago, ferrous alloys have remained
important. Today, many applications of iron and steel can
Extracting aluminium from bauxite
Aluminium is too high in the electrochemical series (reactivity series) to extract it from its ore using
carbon reduction. The temperatures needed are too high to be economic.
Instead, it is extract
