Information @ a Glance


  • Wollastonite, a calcium metasilicate (CaSiO3), has an ideal composition of 51.7% silicon dioxide and 48.3% calcium oxide but can also contain trace to minor amounts of aluminum, iron, magnesium, manganese, potassium, sodium, or strontium substituting for calcium. Wollastonite occurs in
    the form of prismatic crystals that break into tabular-to-acicular fragments.
  • The wollastonite industry is strongly dependent on sales to the ceramics, metallurgical, paint, and plastic industries
  • Worldwide Ceramic applications probably accounted for 30% to 40% of wollastonite sales worldwide, followed by polymers (plastics and rubber) with 30% to 35% of sales, and paint with 10% to 15% of sales. The remaining sales were for construction, friction products, and metallurgical applications.
  • In the USA Plastics and rubber applications were estimated to account for 30% to 35% of U.S. sales, followed by ceramics with 20% to 25%; metallurgical applications, 10% to 20%; paint, 10% to 15%; friction products, 10% to 15%; and miscellaneous, 10% to 15%.
  • Large deposits of wollastonite were in China, Finland, India, Mexico, and the United States. Smaller, but significant, deposits were in Canada, Chile, Kenya, Namibia, South Africa, Spain, Sudan, Tajikistan, Turkey, and Uzbekistan.
  • The acicular nature of many wollastonite products allows it to compete with other acicular materials, such as ceramic fiber, glass fiber, steel fiber, and several organic fibers, such as aramid, polyethylene, polypropylene, and polytetrafluoroethylene in products where improvements in dimensional stability, flexural modulus, and heat deflection are sought
  • Wollastonite production in India is currently from the Belkapahar deposit in the state of Rajasthan by Wolkem Pvt. Ltd. Wollastonite is found within limestone horizons which have been replaced by pyroxenites and gneiss in association with contact metamorphism . After hand sorting, the wollastonite has few impurities and is of high aspect ratio. Reserves are very large and production currently is via open-pit mining.
  • While Wollastonite production from North America dominates the world market, a significant and increasing share of production comes from Europe and Asia, specifically Finland, India, and China.
  • In 2012, China was the leading producer of wollastonite with 300,000 t production of ore concentrate. India ranked second
    with 150,000 t of refi ned wollastonite production, followed by the United States (production withheld), Mexico with 55,200 t, Finland with 11,500 t, Spain with 4,000 t, and South Africa
    with 2,400 t. Small quantities of wollastonite may have been produced in other countries
  • In India,Major deposits of wollastonite have been found in Dungarpur, Pali, Sirohi and Udaipur districts in Rajasthan. Besides, in Ghoda area, Banaskantha district in Gujarat and in Dharmapuri and Tirunelveli districts in Tamil Nadu
  • In India, Production of wollastonite at 183 thousand tonnes in 2010-11 registered an increase of 38% as compared to that in the preceding year due to good demand in the market. There were 2 reporting mines during both the years. The entire production was reported from private sector mines located in Rajasthan
  • Bulk demand for wollastonite in India
    is in the ceramic industry for the manufacture of floor and wall tiles while small quantities are used in asbestos-cement products as a partial
    replacement for short fibre asbestos, paint, insecticide, marine wallboard, and welding rod industries.
  • In India, the reported consumption of wollastonite is estimated at 3,300 tonnes in 2010-11. The ceramic industry consumed almost the entire quantity of wollastonite
  • In India, The total production was at 0.132 million tonnes, which satisfies the demand of wollastonite in the country, but the demand estimate is for 0.2 million tonnes by 2016-17. Moreover, there is an increasing demand for wollastonite in the international market, there is a scope for increase in exports of wollastonite from India in value added form of powder, while considering competition from China and USA
  • Prices : Quoted prices for domestically produced acicular wollastonite, ex-works, were $231 to $265 per metric ton for
    200-mesh, $242 to $276 per ton for 325-mesh, and $489 per ton for acicular wollastonite. Prices for wollastonite from China, free on board, in bulk, were $80 to $90 per ton for 200-mesh and $90 to $100 per ton for 325-mesh
  • U.S. and world production and sales of wollastonite may increase by several percentages in 2013
  • U.S. exports were estimated to have increased from those of 2011 but were still likely be less than 10,000 t.
  • U.S. imports were estimated to be slightly more than in 2011 but were still less than 4,500 t in 2012
  • There is an increasing demand for wollastonite in the international markets, specially in ceramic and plastic industries and in construction activities
  • Since, wollastonite is mined and export by only a few countries in the world, there is a scope for increasing the exports of this mineral from India in value-added form as coated powders
