class 10 science chemistry extraction of metals

Ores: The minerals from which a metal can be profitably extracted are called ores. Metals found at the bottom of reactivity series are least reactive and they are often found in nature in free-state; such as gold, silver, copper, etc. Copper and silver are also found in the form of sulphide and oxide ores.GCSE CHEMISTRY - Extraction of Metals - What is a Metal,,A metal below carbon in the reactivity series (zinc to silver) may be extracted by heating the metal ore with carbon. During the reaction, the metal in the ore is displaced from its non-metal anion because carbon is more reactive than the metal. Carbon is used because it is cheap and readily available (coke and charcoal are both carbon). This form ofSteps involved in Extraction of metals | Winner Science,There are different steps involved in extraction of metals. Let us discuss them one by one: 1. Crushing and Grinding.
