Lime: chemical feedstock, ag-lime, high-calcium limestone Lime (calcium oxide) both as quicklime and hydrated lime are manufactured in Scott County. It is produced by calcining (burning under controlled conditions) high calcium limestone to produce quicklime. Some of the quicklime is crushed and reacted with water to produce hydrated lime.

Some deposits have chemical grades as high as 95% CaCO 3. However, some areas are completely without any suitable limestone deposits. Most of the cost of limestone to the customer is determined by how far away it comes from and how it is shipped. Shipping by barge on water is cheaper than by train which, in turn, is cheaper than shipping by truck.
