Zircons are considered to be the longest-lasting minerals on earth. They are hard, chemically resistant, and contain elements that can be dated, therefore are used in geology a lot. The oldest object found yet is a 4.2 billion year old zircon grain. Zircons are the bases of dating many rocks worldwide.
Zircon sand typically consists of about 65% of Zirconia, 32 % of silica, around 1.15% of aluminium, 0.27 % of Titania. It is a group of minerals that belong to the nesosilicates class. The chemical name is zirconium silicate. The natural color of zircon varies between colorless, yellow-golden, red, brown, blue, and green.
They are found on the surface of the sand. They form placer deposits on the beach, which can be mined in a process known as heavy mineral mining. One of the leading private heavy mineral mining companies in India is VV Mineral.
VV Minerals, India is a family grown business started by Mr. S Vaikundarajan, Chairman of VV Group of companies. They manufacture and export heavy minerals such as Zircon, Garnet, Rutile and Ilmenite.
Commercially, zircons are mined for the metal zirconium which is used for abrasive and insulating purposes. It is the source of zirconium oxide, one of the most refractory materials known.
