How are the less reactive metals extracted? – Wise-Answer
WebMetals are found in ores generally in the form of combination with other types of elements or metals. Thus, as a result, once the metal ore has been extracted from the ground, they need to be converted into its pure metal form. This process of extracting metals from their ore is known as metal extraction. WebMetals 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 metal ores.
