- Dolomite is used in the ceramic industry and in studio pottery as a glaze ingredient, contributing magnesium and calcium as glass melt fluxes.
- Dolomite is used as an ornamental stone, a concrete aggregate as well as in the Pidgeon process for the production of magnesium.
- Large quantities of processed dolomite are used in the production of float glass.
- Dolomite is crushed and sized for use as a road base material, an aggregate in concrete and asphalt.
- Dolomite is sometimes used in its place as a flux for the smelting of iron and steel.
- Dolomite is also used as the substrate in marine (saltwater) aquariums to help buffer changes in pH of the water.
