Abstract
A method for refining a titanium metal containing ore such as rutile or ilmenite or mixtures to produce titanium ingots or titanium alloys and compounds of titanium involves production of titanium tetrachloride by processing the ore with a chlorinating procedure and removing various impurities by a distillation or similar procedures to form a relatively pure titanium tetrachloride. Thereafter, the titanium tetrachloride is introduced continuously into a reactor at the focal point of a plasma under atmospheric pressures of inert gas along with molten metallic reductant for the initial reduction of gas phase titanium tetrachloride into molten titanium drops which are collected in a set of skulled crucibles. Thereafter, further processing is carried out at atmospheric pressures in under inert gas where the titanium is heated by plasma guns to maximize titanium purity and, in a final optional stage, alloying compounds are added under the same controlled environment and high temperature conditions.
