Dolomite A Useful Mineral IspatGuru

2017. 6. 28.  Both the rocks have approximately the same hardness, and they are both soluble in dilute hydrochloric (HCl) acid. The original mineral name ‘dolomie’ was given by NT Saussare, in 1792, in honor of the French geologist Deodat Guy de Dolomieu (1750–1801). Dolomite, the rock, contains a large proportion of dolomite the mineral.

DOLOMITE/ HARD MARBLE. Dolomite, also known as "dolostone rocks" and "dolomite rocks", is a sedimentary rock composed mainly of mineral dolomite, CaMg (CO3)2. Dolomite is present in sedimentary basins around the world. It is thought to have been caused by a postdepositional change of limestone mud and limestone by groundwater rich in magnesium.
