Wollastonite as a most important of these minerals occurs only in a handful of places where it is abundant enough to make mining worthwhile. One of them is Willsboro in New York State (two photos below). It forms when limestone reacts with silicate fluids: CaCO 3 (calcite) + SiO 2 (quartz) → CaSiO 3 (wollastonite) + CO 2 (carbon dioxide)
wollastonite have been identified in Arizona, California, Idaho, Nevada, New Mexico, New York, and Utah; however, New York is the only State where long-term continuous mining has taken place.

Prices for domestically produced wollastonite were estimated to be between $300 to $320 per metric ton. Price data for globally produced wollastonite were unavailable. Products with finer grain sizes and acicular (highly elongated) particles sold for higher prices. Surface treatment, when necessary, also increased the selling price.

Wollastonite occurs in three different forms, depending on its crystallizationmon Wollastonite is known as Wollastonite 1A, indicating that it is one form of Wollastonite that crystallizes in the triclinic system. The "1A" distinguishes it from two rarer forms of Wollastonite, which are scientifically different minerals since they crystallize differently: …

Being a calcium silicate mineral, wollastonite contributes calcium in ceramic glaze mixes. Wollastonite is widely used as a flux in the casting of steel and in the production of paints and coatings. In paints, wollastonite provides rein-forcement, hardening, low oil absorp-tion, and other benefits. In textured coatings, like stucco ...
