For heavy mineral analysis, the sample is passed through a sieve and the grain size fraction 63 to 300 μm used for follow-up heavy mineral analysis, which are investigated using the petrographic microscope. Neither grinding in a crusher, nor disintegration by diluted HCl acid should be done for these very soft sediments.

If the ore is primarily sulfide copper minerals (such as chalcopyrite ), the ore is crushed and ground to liberate the valuable minerals from the waste (' gangue ') minerals. It is then concentrated using mineral flotation. The concentrate is typically then sold to distant smelters, although some large mines have smelters located nearby.

Dolomite serves as the host rock for many lead, zinc, and copper deposits. These deposits form when hot, acidic hydrothermal solutions move upward from depth through a fracture system that encounters a dolomitic rock unit. These solutions react with the dolomite, which causes a drop in pH that triggers the precipitation of metals from solution.
