Current Technology In The Georgia Marble Industry : Crushed And Ground Product Operations Of The Calcium Products Div., The Georgia Marble Co.

AS far back as 40 years ago management made the initial steps toward utilizing the large amount of reject marble produced by the dimension stone quarries in sized products. In 1947 the Calcium Products Div. of the Georgia Marble Co. was organized to manufacture crushed, ground, and screened products from Georgia marble.* It became obvious early in operations that salability of any products of this type was determined by several factors: high calcium carbonate content, whiteness, dryness, and cleanness. Because no reject material could consistently meet these specifications, Calcium Products Div. now operates three underground quarries for raw material feed. In underground operations no stripping is required, surface contamination and trash are eliminated, weather causes no operational difficulties, and the raw material is maintained dry for plant processing.
