Add to ORKGThe increasing importance of tungsten as an industrial metal and the recent discoveries of extensive deposits of low-grade tungsten ores in Montana led to the investigation which is reported in this paper. The purpose of this investigation was to determine if a saleable concentrate could be obtained from one of these low-grade, Montana scheelite ores
