The challenges, such as cumbersome production …

Extraction of Metals from Ores – Different Processes …

The basic extraction of metals from ores has the following steps. 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 pulverisation.
