GCSE CHEMISTRY - Extraction of Metals - What is

Extraction of Metals. What is a Metal Ore?. A solid element or compound which occurs naturally in the Earth's crust is called a mineral.A mineral which contains a high enough percentage of a metal for economic extraction is called a metal ore. Economic extraction means that the cost of getting the metal out of the ore is sufficiently less than the amount of money made by selling the metal.

Reduction of Metals (Extraction from Ore) - A

Reduction of metal halides with metals. In many cases, carbon cannot be used to reduce the metal oxide to the metal as the metal reacts with carbon to form the carbide instead. It is possible to avoid this problem by first converting the ore to the chloride, and then reducing the chloride with a more reactive metal such as magnesium or sodium.

Liquid–liquid extraction - Wikipedia

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 (non-polar). There is a net transfer of one or more species from one liquid into another liquid phase, generally from aqueous to organic.

Metals Non-metals Extraction of high reactivity

Extraction of Metals of high reactivity. Metals of high reactivity; such as sodium, calcium, magnesium, aluminium, etc. are extracted from their ores by electrolytic reduction. These metals cannot be reduced using carbon because carbon is less reactive than them. Electrolytic Reduction: Electric current is passed through the molten state of
