Ore Dressing Methods
Ore-dressing methods fall naturally into two general subdivisions— (1) concentration methods and (2) direct-recovery methods (amalgamation and leaching or wet methods). Concentration methods are employed to remove worthless gangue material and concentrate the valuable minerals of the crude ore in a smaller bulk. Thus, cobbing and …

Dissolution enables dolomite crystal growth near ambient
Given that continental drift also occurs on a timescale of 100 million years, we speculate that an interesting research direction may be to connect dolomite ordering rates to tectonic movement, in which a moving land-sea interface could potentially be a source of dissolution-reprecipitation for massive dolomite generation.
