Specialty Minerals manufactures lime at its Adams, Massachusetts plant— both for internal use in precipitated calcium carbonate manufacture, and for merchant sales. A fluo-solid type kiln is used, which yields a granular quicklime of high reactivity that is dust-free and free-flowing.
Two types of lime are produced: metallurgical grade and chemical grade. The high-calcium metallurgical grade’s high reactivity and low impurity levels make it suitable for many steel desulfurization applications. The chemical grade quicklime is used in many industrial applications.
