Dolomite: Description, Characteristics, and Other FAQs
What Are The Physical Characteristics of Dolomite? Dolomite typically has a Mohs hardness of 3.5 to 4, making it somewhat soft and easy to work with. It's also relatively lightweight, with a specific gravity of 2.8 to 2.9. Additionally, dolomite is chemically inert, meaning it won't react with other materials.

How Lime is Made
The limestone is heated as it moves down the kiln toward the lower end. As the preheated limestone moves through the kiln, it is "calcined" into lime. The lime is discharged from the kiln into a cooler where it is used to preheat the combustion air. Lime can either be sold as is or crushed to make hydrated lime.
