What is Zircon Sand? What is Zircon Sand used for ...

About Zircon. Zircon, also referred to as zirconium silicate (ZrSiO 4), is a co-product from the mining and processing of ancient heavy mineral sand deposits.Mined mainly in Australia, it can be used either in its coarse sand form or milled to a fine powder. Its properties ensure that it is used in many everyday products, including ceramic tiles and medical implants, as well as having major ...

Refined corrosivity testing supports zircon shipments. Zircon sand from the same sample was re-tested at the same laboratory, using the refined test methodology. The results of the re-test, carried out over a seven-day period, showed that zircon sand was not corrosive to metal. Therefore, zircon sand is not a

Analysis of the zircon ages was conducted using published statistical methods including the Kolmogorov-Smirnoff (K-S) test, degree of similarity, degree of overlap, and degree of likeness. Each method compares the four age populations to each other to calculate how alike (or different) they are. The K-S test is used to determine the probability that two samples were derived from different ...
