Low-Silica and High-Calcium Stone in the Newman Limestone

Intervals of high-calcium limestone are present in the low-silica zones. These deposits are potentially suitable for use as rock dust in underground coal mines and as neutralizing agents in surface-mine reclamation and acid-drainage control. The intervals of chemically pure stone in Harlan County may be sufficiently thick to produce by

QUALITY West Plains Mining

For example, if the water body was stormy or muddy poorer quality limestone or shales exist today at that location. If the water body was calm there is less likelihood for contamination and as a result high quality stone exist in present form. The Kentner Creek operation mines Silurian age limestone that was deposited in a unique environment.

Wollastonite Wikipedia

Wollastonite is a calcium inosilicate mineral (Ca Si O 3) that may contain small amounts of iron, magnesium, and manganese substituting for calcium. It is usually white. It forms when impure limestone or dolomite is subjected to high temperature and pressure, which sometimes occurs in the presence of silica-bearing fluids as in skarns or in contact with metamorphic rocks.
