Today, most zircon is produced by mining or dredging zircon-rich sediments. These sediments can be in beach, littoral, or alluvial deposits. Zircon has a specific gravity of 4.6 to 4.7, which is much higher than the typical detrital sediment grain that is between 2.6 and 2.8.
Zircon is a common accessory to trace mineral constituent of most granite and felsic igneous rocks. Due to its hardness, durability and chemical inertness, zircon persists in sedimentary deposits and is a common constituent of most sands.

Zircon is commonly tied up with titanium mineral sand deposits but has very different market applications. It is almost double the US dollar value of rutile. Most of producers of titanium minerals from sand have zircon by-production but the focus on this high-value production is increasing in line with demand driven by China.
Product Price : Get Latest Price We are leading supplier of Zircon Sand, which is composed mainly of zirconium silicate ZrO2. Further, the mineral due to hardness, durability and chemical inertness, zircon persists in sedimentary deposits and is a common constituent of most sands.
Zircon mining in Casamance is contested by the locals defending their sustainable and traditional livelihoods against the mining and weakening of the Niafourang dune. The exploitation is expected to start by October 2017.
Ilmenite, rutile and zircon are the three heavy minerals mined from the sand mines at Sibelco's North Stradbroke Island Operation in Queensland, Australia. The heavy minerals extracted account for 1% of the total sand. The remaining 99% is used in post mining rehabilitation.
Zircon is a well-known mineral that makes an important gemstone of of many colors. Its brilliant luster and fire, combined with good hardness, make it a desirable gem.Natural Zircon with good color and transparency is uncommon; most Zircon crystals are opaque and brownish.
The grade of a typical heavy mineral sand ore deposit is usually low. Within the 21st century, the lowest cut-off grades of heavy minerals, as a total heavy mineral (THM) concentrate from the bulk sand, in most ore deposits of this type is around 1% heavy minerals, although several are higher grade.
Australia and Africa are major producers of mineral sands containing titanium minerals and zircon. A minor constituent of many mineral sands deposits is monazite, which is the main source of thorium. As thorium is radioactive, occupational health provisions are …

Geology. Zircon (ZrSiO 4) is one of the two core product streams from "mineral sands," the other being titanium minerals [ilmenite, leucoxene and rutile].. Deposits of mineral sands are formed along ancient coastlines where the heavier minerals have been concentrated by wave and wind action.
RECOVERY OF ZIRCON FROM SATTANKULAM DEPOSIT IN INDIA—PROBLEMS AND PROSPECTS 69 Introduction Zircon (ZrSiO 4) is the most frequently occurring mineral for the element, zirconium (Zr). It is a common accessory
The main applications for zircon sand are in ceramics, refractories, TV glass and the production of zirconium oxides (zirconias) and zirconium chemicals. The production of glaze emulsions in the ceramics industry was the greatest consumer in 2008 at around 600,000mts.
Southern Ionics is exploiting the heavy minerals Mission Deposit, an ancient beach sand ridge in Charlton and Brantley counties, Georgia, and becomes just the third producer of zircon in the USA, after Iluka Resources Ltd and DuPont Titanium Technologies.

GCO is located on a coastal, mobile dune system starting approximately 50 kilometres north-east of Dakar in Senegal, West Africa, with the deposit extending northwards more than 100 kilometres. The Government of the Republic of Senegal is a valued project partner.
Zircon and rutile are both more valuable than ilmenite, but since zircon grades in most deposits are significantly higher than those for rutile, zircon often is the major economic driver for the development of a mineral sand deposit.
In the sands of ancient beach deposits in southeast Georgia, Southern Ionics Incorporated (SII) is mining zircon sand, which is processed and used in important medical applications, such as artificial hips and knees, as well as in home dialysis units for kidney patients.
