Economic Position Of Western Barite Deposits

From the time of its beginning in the mid-19th century, the American barite industry has had its major development in the eastern and central states. Geologic and economic factors serve to maintain Arkansas, Missouri, and the Southern Appalachian states in the lead position. In earlier days, the major markets for barite were in paint, chemical, and glass manufacturing, and the favored deposits were those which were close to eastern industrial areas; furthermore, the eastern deposits were cheaply mined and required little or no beneficiation. In the last few decades, the use of barite as a weighting medium for muds in rotary oil well drilling has caused a great expansion in the industry, but the marketing picture is still centered outside of the western states-now on the Gulf Coast area where high pressures are common in oil wells. Low cost imported barite, readily available on the East Coast and Gulf Coast, has always been a major marketing factor in the industry. The major barite producing state is Arkansas, with the industry centering about the Magnet Cove area. Missouri ranks second, with production mainly from residual deposits. Several Southestern states are actively producing from residual deposits.
