FT Climate Capital - The metal's role role in the climate crisis is now under scrutiny as companies across the world are racing to reduce their emissions. But the costs and challenges they are facing are significant.

The video is a lecture presentation on the extraction of metals. The presenter begins by discussing how the method used to extract a metal from its ore depends on the metal's reactivity. The lecture then covers the extraction of iron...

This video explains different chemical reactions used for extracting metals from their oxides. The video starts with the simple method of reduction with carbon for metals such as iron, where the metal oxide is reduced, and carbon is...

Learn the basics about recycling metals as a part of the environmental chemistry topic.

Learn the basics about the exchange of oxygen in oxidation-reduction reactions (REDOX) when learning about chemical reactions. In a chemical reaction, oxidation is oxygen GAIN and reduction is oxygen LOSS. A good example of oxidation is...

Since the beginning of atomic testing steel has become weakly radioactive making it useless for applications sensitive to radiation such as in the manufacture of Giger Counters.

Learn about iron alloys as part of metals and their reactivity, within environmental chemistry.
