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.

Zircon sand is mainly used in refractory materials, ceramics, glass, paint, casting industry, etc. 1, refractory materials, used in the production of zircon, zirconium just the quality of the jade fused brick, brick sintered brick, nozzle brick, glass kiln zirconium ramming material, pouring material; 2, ceramics, chemical performance is stable, it is a kind of high quality, low price of opacifying agent, widely used in various construction ceramics, sanitary ceramics, daily-use ceramics, ceramic arts and crafts production, such as in the production of ceramic glaze, using range is wide, can significantly improve the ceramic glaze combined with performance, improve the ceramic glaze hardness; 3, glass: TV industry of colour picture tube, emulsifying glass glass industry; 4, coating: good suspension stability, has good thixotropy and liquidity, besmear to brush, brushless coating mark, low organic matter content, hair volume small, the coating with high intensity, zircon powder has strong ability of chilling to the casting, the adhering sand resistance is good, which can effectively prevent the casting surface defects, the casting surface is bright and clean, easy to clean.Suitable for large and medium-sized steel and cast iron and nonferrous alloy casting.Apply to the sodium silicate sand, clay sand especially resin sand and so on all kinds of sand mold core. 5, casting, with good thermal conductivity, low thermal expansion and good thermal shock resistance and high refractoriness, the characteristics of the heat storage coefficient of zircon sand is bigger also.For the castings have strong chilling effect, refined metal organization, improve the mechanical properties, zircon sand (powder) for large steel thick wall and all kinds of alloy steel castings, as the surface material has the effect of fine grains, commonly used for preparation of surface layer and sanding materials, used in production of stainless steel and so on of investment castings, to improve surface quality and dimension precision of casting.
