Patgowari Dolomite Mine
Besides flux, dolomite is also used as refractory material. High grade dolomite with less than 0.2% iron oxide is used in glass manufacture. The other uses of dolomite in the form of powder include as filler in paints and varnishes and in tannaries and fungicides. In the powdered form, it is used, for dusting in the coal mines. The total reserves of dolomite from Maharashtra State are of 298.65 million tonnes.

MSMC has a Dolomite mine lease at Patgowari village. This mine have been an operating one since last 21 years. The quality of Dolomite present in the mine is suitable for use in Mosaic tiles manufacturing, as a carrier in fertilizer manufacturing and as filler in detergent manufacturing.
