Title: Presence of uranium and thorium in zircon assemblages separated from beach sands of Cox's Bazar, Bangladesh Abstract: Beach sands harbor appreciable amount of radioactive elements such as zircon which contains some important and radioactive elements (e.g. uranium, thorium). Very limited quantitative information is available of such elements in the sand of the beaches of Cox's Bazar ...

These so-called placer deposits are often beach or fossil beach sands and contain other heavy minerals of commercial interest such as zircon and ilmenite. Monazite can be isolated as a nearly pure concentrate by the use of gravity, magnetic, and electrostatic separation. Monazite sand deposits are inevitably of the monazite- composition

Zircon (/ ˈ z ɜːr k ɒ n / or / ˈ z ɜːr k ən /) is a mineral belonging to the group of nesosilicates. Its chemical name is zirconium silicate, and its corresponding chemical formula is Zr SiO 4. A common empirical formula showing some of the range of substitution in zircon is (Zr 1–y, REE y)(SiO 4) 1–x (OH) 4x–y.
A rapidly growing sector for the use of zircon is the production of zirconium based chemicals which are used in the nuclear industry. LKAB Minerals offers Zircon Sand and Zircon Flour for these applications.

[PDF]The foundry market – where zircon is used in foundry sand, coatings, and stucco– is one of the main markets for zircon, vying for a market share of 10-15% along with chemicals and refractories. Demand from investment casting in the automobile and aerospace sectors is growing. Ceramics is the largest market for zircon, accounting for about 51-55%.

Heavy mineral sands are a class of ore deposit which is an important source of zirconium, titanium, thorium, tungsten, rare-earth elements, the industrial minerals diamond, sapphire, garnet, and occasionally precious metals or gemstones.. Heavy mineral sands are placer deposits formed most usually in beach environments by concentration due to the specific gravity of the mineral grains.
Zircon sand has a low expansion coefficient and is very stable at high temperatures. It is used as a refractory material in many foundry and casting applications. One of its most common uses is in the production of ceramics. Zirconium dioxide (zirconia) is produced by heating zircon sand to a high enough temperature to break down the zircon ...
[PDF]Air tabling of zircon-rich non-conductor products containing quartz enables most of the fine quartz present to be rejected without a markedloss of zircon. The coarser quartz in the air table feed can be separated from the zircon by screening one or more air table products, the oversize products containing most of the quartz and little...
