Jul 28, 2012 · 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 ...

The process of grinding the crushed ore into fine powder with the help of the stamp mills is called pulverisation. Concentration of Ores Removel of unwanted materials (, sand. clays, etc.) from the ore is known as ore concentration, ore dressing or ore benefaction. It can be carried out by various ways depending upon the nature of the ore.
This process is known as pulverization. 2. The concentration of ores: The process of removing impurities from ore is known as a concentration of minerals or ore dressing. In metallurgy, we concentrate the ores mainly by the following methods. 3. Hydrolytic method: In this method, we pour the ore over a sloping, vibrating corrugated table with ...
The process of liberation of copper ores depends upon whether they are oxide or sulfide ores. Subsequent steps depend on the nature of the ore containing the copper. For oxide ores, a hydrometallurgical liberation process is normally undertaken, which uses the soluble nature of the ore minerals to the advantage of the metallurgical treatment plant.
