    Health Assessment Document for Talc
    Talc is mined using hand tools, drilling, or blasting methods (Clifton, 1985). Practices for refining talc ores vary greatly. Some operations initially sort the talc by hand according to color and physical characteristics (Clarke, 1979). The latest technology, however, employs flotation separation.
