3.1
zircon sand
sandy ore mainly composed of zirconium silicate (ZrSiO4) which is enriched and extracted from coastal placers, residual placers, alluvial placers, dikes and rocks by physical mining methods such as manual and mechanical methods or chemical methods, and usually contains associated ore. Generally, it is divided into zirconium concentrate, zirconium middling, zirconium coarseore, zirconium deposits, etc.
