Current Status of Titanium Recycling and Related Technologies

The major resource for recycling Ti is currently in-house Ti scrap generated in smelting and fabrication processes instead of postconsumer Ti products, and the actual recycling rate including cascade recycling in the smelting and fabrication industry is high. The major impurities in Ti scrap are O and Fe. High-grade Ti scrap with low O and Fe concentrations is remelted to obtain Ti and its alloys. On the other hand, low-grade Ti scrap with high...
