Limestones and dolomites are sedimentary rock, and are collectively referred to as carbonates because they consist predominantly of the carbonate minerals calcite (CaCO3) and dolomite (CaMg[CO3]2).
Dolomite and limestone are very similar rocks. They share the same color ranges of white-to-gray and white-to-light brown (although other colors such as red, green, and black are possible). They are approximately the same hardness, and they are both soluble in dilute hydrochloric acid. They are both crushed and cut for use as construction materials and used for their ability to neutralize acids. What is difference between limestone and dolomite?
Dolomite is slightly harder than limestone. Dolomite has a Mohs hardness of 3.5 to 4, and limestone (composed of the mineral calcite) has a hardness of 3.
Most of the limestone and dolomite produced is used for construction aggregate for roads and building projects and an aggregate in concrete and asphalt.
Whether you want limestone or dolomie, choose appropriate professional limestone mill and dolomite mill will get benefit.
