| titleOfInvention | Method for smelting titanium anatase ore |
| abstract | PURPOSE: To respectively separate and recover Ti, Fe, Nb, Zr and rare earth elements from a product obtd. by bringing anatase ore into reaction with a gas contg. hydrocarbon in a plasma or high temp. state and constituted of a carbide phase essentially consisting of TiC, a metallic iron phase and the oxides of mainly rare earth elements, Ca and Al by using the method of acid leaching, electromagnetic separation, the distillation of chlorides or the like. n CONSTITUTION: By using a high frequency plasma furnace, a plasma arc furnace or the like, a gas contg. hydrocarbon is formed into a high temp. state or a plasma state, in which pulverized anatase ore is fed, the anatase are is brought into a product constituted of a carbide phase essentially consisting of TiC, a metallic iron phase and an oxide phase of components excluding Ti and Fe. The product is, as it is, subjected to low temp. chlorinating treatment and is separated into mixed chlorides and chlorinated residue. Or, from the above product, by electromagnetic separation, magnetized matters are removed, and nonmagnetized matters are subjected to acid leaching to remove iron content; then, the leached residue is subjected to low temp. chlorinating treatment and is separated into chlorides essentially consisting of TiCl 4 and chlorinated residue; thereafter, by fractional distillation, the chlorides are respectively fractionated into TiCl 4 , FeCl 3 , NbCl 5 and ZrCl 4 ; and the chlorinated residue is fed to an extracting raw material for rare earth metals such as Ce and La. n COPYRIGHT: (C)1992,JPO&Japio |
