From Ore to Finished Product - Copper

The first step in processing the ore removed from the mine is to break the large rocks of ore into smaller pieces. This is accomplished by a variety of subsequent processing steps. 4. Beneficiation of Copper Ore The next step in processing is called beneficiation. This is the first step in concentrating the copper into a more useable form. 5.
