process of crushing ores

Extraction of Metals from Ores – Different Processes Involved

This is how an extraction process is designed. Every constituent is analyzed and then the most suitable process of separating it from the rest is chosen. The basic extraction of metals from ores has the following steps. 1. Grinding and Crushing. The bigger chunks of the ore extracted are crushed and ground in ball mills and crushers.
