Extraction of Metals from Ores – Different Processes Involved

On the other hand, carbonated metal ores are heated in a vacuum for easy extraction of metals. This is called calcination. This is how a concentrated ore is again refined to gather purer metals. This is a gist of how the extraction of metals ores and minerals is performed based on the physical and chemical properties of the impure ores.
