Abstract (English, KR 20090019378 A)
A collecting device having double molten metal for collecting a valuable metal from spent catalysts and a collecting method thereof are provided to use energy efficiently by supplying waste heat in a melting furnace. A collecting device having double molten metal for collecting a valuable metal from spent catalysts includes the followings: two molten metals(20) collected from under the inside of a melting furnace(60); an input pathway(10) of the molten metal formed in a front side of melting furnace; a burner(30) heating the melting furnace in both sides of the melting furnace; a slug outlet(40) discharging gas and slag in the melting furnace; an air infusion pipe(50) supplying combustion air of high temperature to the burner; and a closing unit blocking an outlet(21) of the molten metal.
Redemption.
Have you been redeemed?
If you have been redeemed you have already been to the pit of hell.
Once purified (all the dross and slag removed)
The pure stuff is on the bottom the bad stuff on top.
So it is the bottom of the melting pot that holds the good stuff.
Or the pit.
So when some one tells you that this is from the pit of hell they are
right.
