The radiation impact on the environment from naturally-occurring radioactive materials in zircon sand is an important issue for zirconium product manufacturing enterprises. In this paper, a typical oxychloride production enterprise has been taken as an example to study the radiation effect and environmental pollution during the whole production process.
· Zircon sand process. Zircon sand processing plant is the process of removing impurities from zircon ores and increasing zircon content. Zircon (also known as zirconium)is zirconium orthosilicate. Its chemical formula is ZrSiO4 is one of the most common zirconium-bearing minerals. The zircon ore deposits are mostly seashore placer deposits.
Zircon is a zirconium silicate mineral with a chemical composition of ZrSiO 4. It is common throughout the world as a minor constituent of igneous, metamorphic, and sedimentary rocks. Zircon is a popular gemstone that has been used for nearly 2000 years. Today it serves as a modern birthstone for the month of December.

Zircon''s density allows the grains to be recovered from the other sand minerals by mechanical separation. In the wet concentration plant, the mined mineral sand or ore is washed through a series of spiral separators to separate the heavy minerals from the lighter quartz and clay materials.
The yield of the extraction process was about 83 % at a purity of 97 % zirconia. The major impurity in the final product was found to be 3 % of hafnia (HfO2), which is present in zircon sand as an ...
Zircon, similar to apatite, as an accessory mineral, exists ubiquitously in most types of rocks; and it is rich enough in uranium to permit age determinations down to million years or so. Its atomic composition is ZrSiO4, molecular weight is 183.304 g/mol, A/Z = 2.128, and ionization potential is I = 209.5 eV.
· While demand is rising, ore grades are falling, increasing production costs: as the ore grade drops, more ore must be processed to recover the same amount of Zircon.
· is mainly produced by a chemical production process with zirconium sand . Zirconium products are widely used as corrosion-resistant structural materials in many ﬁelds, such as the Petroleum, Chemical and Energy ﬁelds. The main raw material, zircon sand, is mostly imported (i.e., into China) at present .

Recovery of scandium, yttrium and lanthanides from zircon sand. This is a process for extracting scandium from zircon ore. It utilizes feeding zircon sand to a fluidized bed chlorinator at about 1000° C. to produce a vaporous (principally zirconium and silicon chlorides) phase and a solid residue and recovering scandium from the solid residue.
The recently developed new process based on molten salt-metal equilibrium for Zr–Hf separation shows a great potential for industrial application, which is compact for nuclear grade zirconium production starting from crude ore. In the present paper, the available separation technologies are compared.
About Zircon. Zircon, also referred to as zirconium silicate (ZrSiO 4), is a co-product from the mining and processing of ancient heavy mineral sand deposits.Mined mainly in Australia and South Africa, zircon can be used either in its coarse sand form or milled to a fine powder. Its properties ensure that it is used in many everyday products, including ceramic tiles and medical implants, as ...
baddeleyite. Zircon is used both for its properties as a mineral and as an ore of zirconium and hafnium. Zircon is a byproduct from the mining and processing of heavy mineral sands for rutile and ilmenite. Zirconium and hafnium occur together in ores at ratios of about 50:1.1 Zircon sand is …
· The decomposition process for zircon sand concentrate using mixed base of sodium hydroxide partly replaced by calcium oxide was inrestigated. It is found that the decomposition rate of zircon gradually increased with the increase of the reaction temperature and time. The decomposition rate is over 97% with the conditions that CaO/zircon molar ratio is 0.25 ∼ 0.75 at 800 °C for 1 h.
Zircon samples, gathered from Yongsanpo, Korea, were separated through magnetic separator and pulverized by ball mill over 250 mesh. In the alkali fusion process, it is considered that zircon is decomposed not only into sodium zirconate but also into a comparatively large part of complex compound of zirconium and silicon in a sodium salt such as sodium silicozirconate.
One of the important routes for the production of zirconia is by chemical treatment and removal of silica from zircon sand (ZrSixOy). We present here a completely green chemistry approach toward enrichment of zirconia in zircon sand; this is based on the reaction of the fungus Fusarium oxysporum with zircon sand by a process of selective extracellular bioleaching of silica nanoparticles.
