What is Extraction and Refining of Metals about?
Metals occur naturally in both free and combined states depending on their reactivity. Less reactive metals like gold and silver are found free, while more reactive metals form oxides, sulfides, and carbonates. Extraction of metals involves processes like enrichment, roasting to convert sulfides to oxides, and reduction using carbon or electrolysis. Refining removes impurities, and alloying improves metal properties. Corrosion occurs when metals react with air and water to form oxides or salts, but can be p
