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 as a molten slag, by processing the ore in a chlorination procedure and removing various impurities by a distillation or other procedure to form a relatively pure titanium tetrachloride (TiCl4). Thereafter, the titanium tetrachloride is introduced continuously into the focal point of a plasma reactor in a molten magnesium, sodium, hydrogen, lithium, potassium, rubidium, cesium, francium, beryllium, calcium, strontium, barium or radium environment for the initial reduction of gas phase titanium into molten titanium drops which are collected by a set of skulls. Thereafter, further processing is carried out in a controlled environment and the titanium is heated by plasma guns in order to maximize titanium purity and, in a final optional stage, alloying compounds are added under the same controlled environment and high temperature conditions.
