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.

| GEOLOGY |
The deposit is exposed at several places in the area and it occurs as successive of beds, which can be traced for a long distance uninterruptedly at places. This indicate lithological uniformities of the deposit. The entire sequence of the rock formation consist mainly of Dolomite strata, lying steeply in general. Such a disposition implies depth persistence of the ore body. The area is covered in the toposheet No.55 O/7 & 55 O/3 between latitude from 21024’ to 21024’30” and longitude from 79013’ to 79014’.
The lease area is spread over plain ground, having low relief and gentle slope towards south. The highest and lowest contours passing through the area are at 324 meter and 315 meter above the MSL respectively.
The rocks in the area belongs to Sausar group of Precambrian age.
