Metallurgy - Wikipedia

2019-4-23 · Extractive metallurgy is the practice of removing valuable metals from an ore and refining the extracted raw metals into a purer form. In order to convert a metal oxide or sulphide to a purer metal, the ore must be reduced physically, chemically, or electrolytically.. Extractive metallurgists are interested in three primary streams: feed, concentrate (valuable metal oxide/sulphide), and

Magnesium oxide | Podcast | Chemistry World

Magnesium oxide is a compound of a metal with a non-metal, so – as you would expect – it is held together with ionic bonds. It has the same structure as NaCl but because it is made of Mg 2+ and O 2 – ions, rather than the singly charged Na + and Cl – ions, there is a much stronger attraction between the ions. This means it takes a lot

Lead - Element information, properties and uses | …

The ancient technologists blanched the dull metal by placing lead strips in pots with vinegar, and shutting them away in a shed full of animal dung. The vinegar fumes and gas from fermenting dung conspired to corrode lead into lead white. Heat this gently, and it turns yellow: a form of lead oxide known as litharge or, in the Middle Ages, massicot.
