how is wollastonite ore processed


Wollastonite is a naturally occurring calcium metasilicate, composed of calcium oxide and silicon dioxide. It is a white mineral that occurs in a needlelike form; aspect ratios range from 3 to 20. It has a high melting point, high pH (9.9), and a specific gravity of 2.9, and it exhibits low moisture absorption.
