MINERAL AND ROCK RESOURCES LECTURE NOTES I Introduction Eight elements (O, Si, Al, Fe, Mg, Ca, Na, and K) make up 98% of the earth's crust Many important elements are found, on average, in the crust in very small amounts (ppm ­ ppb) Finding these elements in high concentrations is the exception and requires unusual geologic process...
Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgyThe primary operations are comminution and concentration, but there are other important operations ....
