Abstract:
The present invention relates to a method for separating mineral impurities from calcium carbonate-containing rocks by comminuting the calcium carbonate-containing rocks to a particle size in the range of from 1 mm to 250 mm, separating the calcium carbonate particles by means of a dual energy X-ray transmission sorting device.
