احصل على السعرThe extraction of raw minerals begins with the mining of rich ores, which are then cut up in crushers and grinders. The pieces of rock initially weighing tonnes are ground down to a few tenths of a millimetre. This grinding process, which often covers six decimal orders of magnitude of the particle size, is carried out in several steps.
