RECOVERY OF ZIRCONIA FROM ZIRCON SANDS

RECOVERY OF ZIRCONIA FROM ZIRCON SANDS The use of zirconia in many fields has grown enormously. The major and cheapest source of zirconia is zircon sand. Despite this, the decomposition of zircon is not easy to achieve due to its stability. Considering the structure of zircon, which is extensively discussed in the literature [3. 9, la, 16, 47], this stability is quite understandable. Various
