iaspore is a dimorphous form of boehmite, under unclassified, not-known and other grades with chemical composition Al O .H O D 2 3 2 (Table - 1). (betamonohydrate of aluminium). It is an important constituent of bauxite. Because of its good PRODUCTION, STOCKS & refractory properties, it is used chiefly for making high-alumina refractory bricks. It is also PRICES used as a filler in plastic industry. The production of diaspore at 16,030 tonnes in 2012-13 registered a decrease by 33% as compared to that in the previous year. RESOURCES Diaspore occurs as thin veins, stringers and The entire production of diaspore was geode-like bodies in association with pyrophyllite reported as an associated mineral by 13 in and Madhya Pradesh where the pyrophyllite mines. Five principal producers host rock mainly comprises granite, quartz and accounted for 95% of the total production during pyrophyllite of Super Group, and as the year. The private sector accounted for almost a common constituent of bauxite in Jammu & entire production of diaspore during the year. Kashmir. Uttar Pradesh being the leading As per UNFC System of resource producer of diaspore contributed about 55% classification, the total resources of diaspore as of total production in 2012-13. The remaining 45% on 1.4.2010 are placed at 5.98 million tonnes of production was reported from Madhya Pradesh which about 63% are located in Madhya Pradesh, Pradesh (Tables - 2 to 4). 37% in Uttar Pradesh and a nominal quantity in Mine-head stocks of diaspore at the end of Jammu & Kashmir. About 2.86 million tonnes 2012-13 was 6,436 tonnes as against 6,293 tonnes (48%) of these resources are placed under reserves at the beginning of the year (Table -5). category. Out of the total resources, more than 76% are grouped under refractory grade, less than Prices of diaspore are furnished in the General 1% in ceramic grade, while 23% resources fall Review on Prices.
