The radiation impact on the environment from naturally-occurring radioactive materials in zircon sand is an important issue for zirconium product manufacturing enterprises.
milling of zircon creates dust which may be inhaled. In the process of separating zircon from other mineral sands, and in the process of its bulk handling, small dust particles may also be generated. Internal exposure could also be caused by ingestion, but very large quantities would need to be ingested to cause a measurable radiation dose.

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.It is one of the most common zirconium-bearing minerals. The zircon ore deposits are mostly seashore placer deposits.
With silica beads, impurities can attain a concentration enough to inhibit many enzymes and reduce the affect the amount of analytes. Quality control analysis of raw silica and zirconium beads has identified dust, hair, and insects as contaminants. Beads need to be cleaned prior to use, one such accepted process is to acid wash.
