Dolomite may form as a hydrothermal replacement mineral and, as such, is especially abundant as a gangue mineral in the ore deposits of the Upper Mississippi Valley zinc-lead district in southwestern Wisconsin. Ferroan dolomite appears in several of the state's Precambrian iron formations. Finally, dolomite locally occurs in the state in marbles.

The separation of minerals from gangue is called mineral processing. Oftentimes, inefficient processing methods can produce gangue that still holds an ample amount of valuable minerals. As values of minerals increase, it can even be profitable to …

Complete separation of value minerals from gangue minerals is not always possible when using froth flotation, especially for fine and ultrafine minerals due to the mechanical transportation of hydrophilic gangue minerals by the floated water. The fine and ultrafine particles typically refer to those particles that are less than 20 μm and 10 ...

Un minerai se compose le plus souvent de la (ou des) substance(s) utile(s), d'une gangue stérile et parfois de substances nuisibles (par exemple, du phosphore dans du fer ; de l'arsenic ou du bismuth dans de l'étain).
