Life cycle assessment comparison between zircon and alumina sand
Sand Milling: Zircon sand used in the ceramic sector needs a smaller particle size than the grain size output by the MSP process. The zircon milling phase can be either wet or dry grinding, and this study considers both alternatives. Alumina from the Bayer process may need a reduction in grain size. This is similar to zircon but less …Web

Zircon Sand: An Important Raw Material | SpringerLink
Above all, zircon sand serves as a raw material for the production of powdered zirconium oxide (Sect. 12.1 in Chap. 12 ), a very important ceramic material today. Only a fairly small proportion of the world's zircon is used to produce metallic zirconium (Sect. 6.2 in Chap. 6 ). Nevertheless, this use of zircon sand plays an important role, as ...Web
