- 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limestone horizons which have been replaced by pyroxenites and gneiss in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.
- China was
the leading producer of wollastonite production of ore
concentrate. India ranked second
with of refined wollastonite production, followed by the
United States , Mexico Finland , Spain , and South Africa ; 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, there is 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 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
- U.S. and world
production
and sales of wollastonite may increase by several percentages in 2013
- 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
