Reduction of Metals (Extraction from Ore)

Reduction of Metals (Extraction from Ore)

Extraction using carbon. Metals such as zinc, iron and copper are present in ores as their oxides. Each of these oxides is heated with carbon to obtain the metal. The metal oxide loses oxygen, and is therefore reduced. The carbon gains oxygen, and is therefore oxidised. If playback doesn't begin shortly, try restarting your device.

Liquid–liquid extraction

Liquid–liquid extraction

Liquid–liquid extraction (LLE), also known as solvent extraction and partitioning, is a method to separate compounds or metal complexes, based on their relative solubilities in two different immiscible liquids, usually water (polar) and an organic solvent (nonpolar). There is a net transfer of one or more species from one liquid into another liquid phase, generally from aqueous to organic.
