High-Carbonate, Low-Silica, High-Calcium Stone In The High Bridge Group (Upper Ordovician), Mason County, North-Central Kentucky, Warren H. Anderson, Lance S. Barron

Information Circular--KGS

The High Bridge Group (Middle Ordovician) of northeastern Kentucky is a major source of limestone and dolomite for construction, agricultural, and industrial stone. These industries require carbonate rocks of high chemical purity. Chemical analyses of foot-by-foot samples from a Mason County core show that three zones of high-calcium and several thick zones of high-carbonate and low-silica stone are present in the High Bridge at a mineable depth. Mason County is located in northeastern Kentucky, on the Ohio River, and offers river access to transportation to the metropolitan Covington-Cincinnati market and the northern portion of the Eastern Kentucky Coal Field for …

Use Of Limestone, Lime, And Dolomite For So2 Emission Control In Kentucky, Garland R. Dever Jr.

Information Circular--KGS

Flue-gas desulfurization and atmospheric fluidized-bed combustion systems for sulfur dioxide (SO₂) emission control have been installed at 13 coal- and gas-fired plants and one research laboratory in Kentucky. Limestone, lime, and dolomite are the principal SO₂ sorbents used in these systems.

Nine coal-fired, electricity-generating plants in the State have installed wet-scrubbing systems for flue-gas desulfurization. Lime-based scrubbers are using Thiosorbic® lime, produced from the Camp Nelson Limestone (Ordovician) of north-central Kentucky, and carbide lime, a byproduct from the manufacture of acetylene in Louisville. Limestone-based scrubbing systems at three of the plants have used stone from the Warsaw, …
