First claim
Opening claim text (preview).
1 - 8 . (canceled) 9 . A method for recovering a minor metal and/or rare-earth metal from a post-chlorination residue in titanium smelting, the method comprising: classifying the post-chlorination residue into bigger particles and smaller particles; and recovering the smaller particles, wherein the minor metal and/or rare-earth metal is one or more metal selected from the group consisting of Sc, V, Nb, Zr, Y, La, Ce, Pr, and Nd. 10 . The method according to claim 9 , further comprising recovering the minor metal and/or rare-earth metal from the smaller particles. 11 . The method according to claim 9 , wherein the minor metal and/or rare-earth metal is Sc and/or V. 12 . The method according to claim 9 , wherein the classifying is wet classifying. 13 . The method according to claim 9 , wherein the classifying is performed based on the criteria of 55 μm or less. 14 . The method according to claim 9 , wherein the classifying is performed based on the criteria of 40 μm or less. 15 . The method according to claim 9 , wherein the classifying is performed based on the criteria of 25 μm or less. 16 . The method according to claim 9 , the method further comprising: recovering Sc from the smaller particles; and recovering V from liquid obtained by the recovering of Sc.
