  • 20.1 Metal Deposits Physical Geology

    Looking at copper, for example, we can see that while average rock has around 40 ppm (parts per million) of copper, a grade of around 10,000 ppm or 1% is necessary to make a viable copper deposit. In other words, copper ore has about 250 times as much copper as typical rock.

  • Geology: What is a Mineral Deposit? — Mining Focus

    The degree of concentration is called the "grade" of a mineral deposit. An "ore deposit" is a mineral deposit which has high enough grades of metal that makes it economic to mine. Essentially this means that per tonne of rock containing the desired minerals, the costs of removing the minerals from the rock and separating the metal from the

  • Iron Ore Pelletizing Process: An Overview IntechOpen

    Jul 10, 2017· The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed.
