well, you have to go back into the temple of the ocean king and put the crystals in their proper pedestals in this order.
1. Square
2. Circle
3. Triangle
Then when you go in there will be an earthquake and there will be more temple! Beat that part, but don't get seen by the phantoms, cause thy'll teleport to you! when you beat the part and get to the almost bottom (the bottom part you need the phantom sword to get to) and there's a cheast there with a sea chart! the last pure metal is on the island with the tornado in front, so go to the other island and... well... everything unfolds until you get the metal!
you get the third precious metal for the phantom sword.
its in the last temple for the pure metal
beat the ice temple
you get it in the goron temple while getting the first pure metal
In "The Legend of Zelda: Phantom Hourglass," the last metal you need to collect is called the "Phantom Hourglass." You can find it by exploring the Temple of the Ocean King. After completing the various floors and defeating the Phantom enemies, you'll ultimately obtain the final piece of this crucial item for your quest.
Three metals that when melted together can make the phantom sword. These metals are in The Legend of Zelda Phantom Hourglass.
look or the third or go back and search mercay island
there is no yellow pure metal
In Mutoh's Temple, on the Isle of the Dead

phantoms are the metal guards in the ocean king temple (the legend of Zelda phantom hour glass) and in the tower (spirit tracks )
