Mineral sand deposits are formed from the erosion and weathering of preexisting igneous rocks such as granite, pegmatite and basalt. Over 60 to 200 million years the combinations of wind and water from ancient rivers and seas have leached the minerals from their past rocks and concentrated them into beach and dune deposits.
· The objective of this study was to characterise and optimise the De Wet's zirconium extraction processes for the beneficiation of zircon sand into high purity zirconia and zirconium chemicals. However, at each process step some factors were varied fusion temperature, reactant mole ratios and composition of leach solutions. Attention was also paid to reducing the total number of .
· The foundry market – where zircon is used in foundry sand, coatings, and stucco– is one of the main markets for zircon, vying for a market share of 1015% along with chemicals and refractories. Demand from investment casting in the automobile and aerospace sectors is growing. Ceramics is the largest market for zircon, accounting for about 5155%.
