DOLOMITE

Dolomite is a carbonate mineral and sedimentary rock composed mainly of calcium magnesium carbonate, with the chemical formula CaMg(CO?)?.

In simple terms:

• ? As a mineral: dolomite contains calcium (Ca) and magnesium (Mg).

• ?? As a rock (dolostone): it forms when limestone is altered by magnesium-rich fluids in a process called dolomitization.

Key characteristics:

• Usually white, gray, or yellowish

• Harder than limestone

• Reacts weakly with cold hydrochloric acid

Common uses:

• Agriculture (to neutralize acidic soil and add Mg & Ca)

• Construction materials

• Glass, ceramic, and steel industries
