Steps 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. First of all, ores are crushed into a fine powder in big jaw crushers and ball mills. This method is called pulverization. 2. Concentration (Dressing) of ores. The technique of removing gangue, the rocky impurities like Sio 2 present in an ore, is called concentration of an ore ...
