Zircon, also known as zircon silicate (ZrSiO4), is found in ancient mineral sand deposits. In the form of crystal sands, zircon is typically brown, but could also vary from colourless to yellow-golden, pink and red to blue and green.
The majority of zircon sand is mined in the African continent particularly Nigeria. Current annual global production is in excess of one million tonnes. Almost half of the zircon produced globally is consumed by China, with other significant consuming regions including Europe, North America, Asia-Pacific and India.
With our robust warehouse in Lagos the Southern part of Nigeria we can export 1000MT of this product per month.
Zircon sand finds applications to be used in ceramics, refractory, foundry, electronics, zirconium compound, and other fields, it is also used in the preparation of nuclear reactor structural materials and control rod with zirconium and hafnium as irreplaceable raw minerals making it a strategic mineral.
It is used in ceramics as a major end-user, zircon sand is used as a glaze emulsion is ceramics such as glazed floor tiles, wall tiles, sanitary ware, and tableware.
Properties of Zircon Sand
Zircon is crystal and shows the structure of the quarter column. It usually occurs with ilmenite rutile, sillimanite, etc. in beach sand and is refined by water, electricity, and magnetic beneficiation process.
Pure zircon is a colorless and translucent crystal. It appears yellow, orange, red, and brown with different origins. Its hardness is 7.8, specific gravity 4.6-4.71, refractive index 1.93-2.01, and the melting point of 2550 C.
Zircon sand is generally found in land of ancient coastlines,some of which can be found very far inland,where the heavier mineral sands formed hardened deposits.These deposits are typically mined via dry or wet(dredge)mining techniques.
