Extraction of Metals from Ores – Different Processes Involved
This is how an extraction process is designed. Every constituent is analysed 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. Grinding and Crushing. The bigger chunks of the ore extracted are crushed and ground in ball mills and crushers.

From Ore to Finished Product
Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.
