EXHIBIT D <br /> TABLE D.(G).1 PRIMARY AND SECONDARY COMMODITIES 3 of 3 <br /> Category Product o Applications <br /> Secondary Zircon ZrSiO4 a Ceramics Industry:Zircon is extensively used in the production of ceramics,particularly in the Yes <br /> manufacture of tiles,sanitary ware,and tableware.It acts as an opacifier,imparting a white, <br /> opaque appearance and improved strength and toughness to ceramic products. <br /> • Refractory Materials:Due to its high heat resistance,zircon is used in the production of <br /> refractory materials,like furnace linings and foundry molds.It is especially valuable in high- <br /> temperature applications where robust and heat-resistant materials are needed. <br /> • Foundry Sands:Zircon's high thermal stability makes it an excellent material for use in foundry <br /> sands for casting metals.It can withstand the high temperatures of molten metal without <br /> breaking down,ensuring the precision and quality of cast metal products. <br /> • Zirconium Production:Zircon is the primary source of zirconium metal,which has applications <br /> in nuclear reactors due to its low neutron absorption characteristics.Zirconium is also used <br /> in the production of super alloys and in various chemical applications due to its corrosion <br /> resistance. <br /> 22 <br /> HARDROCK/METAL MINING REGULAR(112)APPLICATION Au Pt Industries LLC I PO Box 1424-Edwards,Colorado 81632 1970 306 1 784 <br />
