How are metal ore obtained
WebSolution. The chemical process which is used for obtaining a metal from its oxide is known as reduction. In this process, metal oxides are reduced to their respective metals by using suitable reducing agents such as carbon or by using some highly reactive metals to displace the metals from their oxides. For example, zinc oxide is reduced to ... WebIron is the backbone of the world we have built around us and it is the basic ingredient of steel (iron plus carbon). Iron is a very useful metal because it can be mixed with other metals to make a whole variety of 'alloys' which are even stronger and don't rust easily and can be shaped into products from cars to pins, household appliances to buildings, …
