Distribution Of Zirconium Resources

Zirconium resources There are more than ten kinds of zirconium bearing ores. Only zircon and baddeleyite are commercially available. Zirconite, also known as zircon, is the most widely distributed zirconium mineral. It is mainly produced in the United States, Brazil, India, Australia, China and CIS. Its main composition is ZrO2·SiO2. The theoretical components are ZrO 267.01 % and SiO233.99 %. The content of various impurities in zirconite ore is: Fe2O3) 0.5% ~ 5.0% and a small amount of CaO,. MgO, TiO2, etc. Plagic zircons are mainly found in Brazil and Sri Lanka. China's reserves are small. The main ingredient is ZrO2. The industrial oblique zircon contains 275% ~ 85% ZrO, the main impurities are Fe2O32% ~ 5%, SiO210% ~ 20% and a small amount of A1203 and TiO2. Mineral density is 5.7 g/cm3 Mohs hardness 6.5.
