A thermic mixture is made by mixing aluminum powder and iron oxide. Sometimes it can be pure iron ore. This can be used to weld cracks in railway tracks, in rails. If you find there is a crack, then you make a mould around it, put this mixture and simply ignite it. Reaction takes place, molten iron produced, fills the gap, and the rail is welded.

22.4: Beneficiation
Beneficiation may involve physical or chemical processes. Often, as in the case of panning for gold, the desired ore or metal is denser than the gangue. The latter can be suspended in a stream of water and flushed away. The iron ore magnetite, Fe 3 O 4, is ferrimagnetic. It can be separated from abundant deposits of taconite by grinding to a ...
