Study Notes
Alloys
- An alloy is a mixture of two or more metals, or a metal and a nonmetal that improves the usefulness of the metals.
Common Ores
- Sodium is extracted from Rock Salt, which is composed of Sodium Chloride
- Calcium is extracted from Chalk, Limestone, Marble that are composed of Calcium Carbonate
- Magnesium is extracted from Magnesite, which is composed of Magnesium Carbonate
- Aluminium is extracted from Bauxite which contains Aluminium Oxide
- Zinc is extracted from various ores: Zinc Blende, Calamine and Zincite which contain Zinc Sulphide, Zinc Carbonate and Zinc Oxide respectively.
- Iron is extracted from Haematite, Magnetite, Iron (III) Tetra Oxide which contain Iron Oxide and Iron (III) Tetra Oxide respectively.
- Copper is extracted from Malachite and Calamine that are composed of Copper(II) Carbonate
- Mercury is extracted from Cinnabar which contains Mercury(I) Sulphide
Extraction Of Metals
- Metals high in the reactivity series are stable and require electrolysis for extraction.
