Limestone Mining - Michigan State University
Most of the chemical uses of limestone, and these are by far the most important, require the stone to be as nearly pure and high in calcium content as possible. Michigan is fortunate in having large deposits of very pure, high calcium stone in the northern part of the state, some of which are conveniently located on or near the shores of the Great Lakes. Thus, quarries were opened in these ...
