465The Mineral Industry of Rhode Island This chapter has been prepared under a Memorandum of Understanding between the Bureau of Mines, U.S. Department of the Interior, and the Rhode Island Department of Natural Resources, for collecting information on all nonfuel minerals. By Doss H. White, Jr.' The value of nonfuel mineral production in Rhode Island in 1978 and 1979 added $7.5 million and $7.9 million, respectively, to the economy of the State. In terms of value, over 90% of the State's mineral production was sand and gravel, which was used pri. manly by the construction industry. Trends and Developments.—Except for some construction materials, the nonfuel mineral requirements of Rhode Island's industry were imported. This included all metals and most chemical and industrial materials. Of approximately 300,000 industrial workers in the State, only 300.400 were directly engaged in mineral extraction. However, approximately 11,000 were employed in the mineral-dependent construc tion industry, and 25,000 were employed in processes or manufacturing that involved stone, clay, glass, primary metals, and fabricated metal products. An additional 32,000 workers were associated with industries that relied upon mineral-derived materials. From 1970 through 1979, value of the State's mineral production increased more than 40%. Gains were recorded for all years except 1971-1972 and 1977. The decrease in value of mineral production in 1971 and 1972 reflected reductions in the mineral industries of five other New England States, which were caused by recessionary pressures on the region's economy. The slight drop in value in 1977 was due to a decrease in sand and gravel sales in Kent County.
