Aluminium foils are used in the food industries for wrapping food. The dust of this metal is used in paints. It is used in the extraction of manganese and chromium from its oxides. As it is a soft metal and can be moulded into any shape it is used in the manufacturing of storage cans. After iron, aluminium is the most commonly used metal.
به خواندن ادامه دهیدExtraction of metals. The process of extracting metal ores buried deep underground is called mining. The metal ores are found in the earth's crust in varying abundance. The extraction of metals from ores is what allows us to use the minerals in the ground. The ores are very different from the finished metals that we see in buildings and bridges.
