    2021-3-20  The extraction process is only partially efficient and, as a result, a percentage of the desired minerals are left behind in the mine tailings. The extraction process may also concentrate unwanted minerals in the tailings. As a result of the crushing and grinding (milling) processes, the large pieces of rocks are turned into small tailings particles.

  • Effect of mechanical grinding on pozzolanic activity

    2019-4-20  In particular, the relative crystallinity of mineral phases of muscovite is decreased to 37% after an 80-min grinding. Ground tailings possess higher pozzolanic activity compared with that of raw tailings in an alkaline environment, and the activity of mechanically activated tailings is gradually increased with grinding time.
