quartz mills are used for ore samples

Barite - Arkansas

The flotation mills typically utilized barite ore containing about 50 percent barite. The result was a concentrate composed of 92 to 94 percent barite. Total production of Arkansas barite concentrates is 9 million short tons (1939-1983 inclusive) - 8 million short tons from the Chamberlain Creek deposit alone valued at ~ 70 million dollars.
