Precipitated Calcium Carbonate PCC Minerals

Precipitated Calcium Carbonate PCC Minerals

PCC production in the U.S. dates from 1938, when the C.K. Williams Company in Adams, Massachusetts, began to make PCC using the limestone from their adjacent mine. This plant was acquired by Pfizer in 1962, and became part of the Performance Minerals group of SMI on the formation of our parent, Minerals Technologies Inc., in 1992.

Emissions from the Cement Industry

Emissions from the Cement Industry

May 09, 2012 The production of cement releases greenhouse gas emissions both directly and indirectly: the heating of limestone releases CO 2 directly, while the burning of fossil fuels to heat the kiln indirectly results in CO 2 emissions. The direct emissions of cement occur through a chemical process called calcination.
