  • From Ore to Finished Product - Copper

    2020-6-2  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.

  • Chapter 2. Production and Processing of Aluminum

    1999-5-7  The economical operation of the Bayer process requires the rational use of energy for steam generation and calcining. Inexpensive fuel is desirable because the process needs a large amount of thermal energy.
