硅灰石目前在许多方面都得到利用,既用作染料,塑料和橡胶的填料,也用作各种纤维质物料的代用品。此外,硅灰石还用作玻璃和陶瓷制品的组分。安大略有一个大型硅灰石矿床,位于多伦多东北175公里的姆拉莫尔进口处。按地质条件这个矿床产于花岗岩和碳酸盐岩石之间的接触带。而在新形成的矽卡岩中见有清晰的分带性。硅灰石矿带毗连花岗岩,其次是透辉石和透闪石带,再其次是未蚀变的白云石-石英-方解石岩层。根据化学成分、矿物组成和粒度,该矿床的矿石具有很好地可选性,主要用浮选法完成。精矿适于用作陶瓷填料。
Wollastonite is currently used in many ways, both as a filler for dyestuffs, plastics and rubbers, and as a substitute for various cellulosic materials. In addition, wollastonite is also used as a component of glass and ceramic products. Ontario has a large wollastonite deposit located at the entrance to Mmormore, 175 kilometers northeast of Toronto. According to geological conditions, this deposit is produced in the contact zone between granite and carbonate rock. There is a clear zonation in the newly formed skarn. The wollastonite belt adjoins granite, followed by diopside and tremolite belt, followed by unaltered dolomite-quartz-calcite rock formation. According to the chemical composition, mineral composition and particle size, the deposit of the ore has good selectivity, mainly by flotation method. Concentrates suitable for use as ceramic filler.
