Zirconium is a chemical element with the symbol Zr and atomic number 40.
The complex plant matrix along with a wide polarity range and unstable chemical properties of PGRs hinder their trace analysis. In order to obtain a reliable and accurate result, a sample pretreatment process must be carried out, including eliminating the interference of the matrix effect and pre-concentrating the analytes.
Concentrating plants have actively promoted the increase in zircon sand prices, and downstream zirconium product prices have also risen in tandem. However, as domestic demand growth momentum is insufficient, the product prices in the zirconium market have also begun to adjust steadily.
