NEET UG : Extraction of Iron, chemistry by unacademy
Pure metallic iron is not usually found in the earth's crust. Therefore, extracting metal from ore is the only way to obtain usable iron. Extraction of iron from its ore is a lengthy process and requires smelters and furnaces. These furnaces should be capable of reaching a temperature of 1500 °C. Let us study the iron extraction process in ...
