The Dolomite Problem Discover Magazine

But for certain sludge-dwelling bacteria, making dolomite is no problem at all. There was a time when Earth made dolomite in great piles--piles like the Dolomite Mountains, in the Italian Alps, where French mineralogist Déodat de Dolomieu discovered the mineral in 1791. Today, though, dolomite forms in only a few select salt flats and lagoons.

3.1. Characterization of dolomite ore The chemical analysis of New-Valley dolomite ore is given in Table 1. It is clear that, the theoretical MgO content in pure dolomite mineral is 21.875%, this indicates that, the purity of dolomite ore is about 75.66%. The ore contains a high amount of calcium oxide which causes the problems after solid/liquid
