  • How Is Copper Formed? | Reference.com

    As the larger rock continues to solidify, the fluid rich in copper moves into cracks, eventually solidifying as well. Because the copper solidifies later than other minerals within the larger rock, the final deposits have a high concentration. Copper appears most frequently in deposits in which lead, silver, gold and zinc are also present.
