WHAT IS CALCIUM OXIDE/QUICKLIME?
Calcium oxide (CaO) or quicklime can be classified as either high calcium or dolomitic. High calcium quicklime has typically >97% CaO with magnesium oxide (MgO) levels less than 3%. At Mississippi Lime, our high calcium oxide (CaO) content is a result of our 98.5% pure calcium carbonate (limestone). Dolomitic quicklime generally contains > 40% MgO along with the calcium oxide.
