| Abstract Scope |
Titanium alloy turning scrap (TATS) is a type of solid waste generated during the machining of titanium alloys. The titanium content in TATS is relatively high, making it extremely valuable. However, due to the presence of oil and impurities, TATS have not yet been utilized in high-value-added applications. A short-process method for recovering titanium from TATS via low-temperature roasting and dry electrostatic separation has been proposed in this study. The results indicate that the titanium in TATS included metallic Ti, TiO2, and low-valent TixOy, the impurity was primarily Al2O3. The conductivity of titanium-containing components and impurities was significantly different. Through low-temperature roasting and dry electrostatic separation, effective removal of impurities from TATS and efficient enrichment of titanium were achieved. Under optimized conditions, the oil was completely removed, and the titanium grade was increased to 56.80%, with a total impurity (Al, Fe, Ca, Mg, and Si) content of only 5%. |
