Extraction of Metals from Ores – Different Processes Involved
1. Grinding and Crushing. The bigger chunks of the ore extracted are crushed and ground in ball mills and crushers. It helps to increase the surface area of the chunks for better chemical actions later. In technical terms, it is called pulverization. 2. Concentrating the Ore. This step concentrates the ore by performing the removal of impurities.
