Method for Producing Zironyl Sulfate Solution from Zircon Sand

摘要

The Bureau of Mines has carried out investigations on a method for producing zirconyl sulfate solution from zircon sand, comprising (1) reacting zircon sand with molten NaOH, (2) leaching the resultant fusion frit with water to remove sodium silicate and to convert sodium zirconate to hydrous zirconium oxide, and (3) leaching the hydrous zirconium oxide from unreacted sand with hot, dilute H2SO4 to produce crude zirconyl sulfate solution. A preliminary cost estimate is included.
