Preparation and Chlorination of Titanium Carbide from Domestic Titaniferous Ores

  • Description:
    The Bureau of Mines conducted laboratory and larger scale studies on samples of domestic perovskite and ilmenite ore concentrates to devise a procedure for recovering tic from these ores. From the concentrates, mixtures of titanium and calcium carbides were produced. The carbides were then ground and reacted with water. This reaction decomposed the cac2 to acetylene and hydrated lime and simultaneously liberated the tic. Using a combination of elutriation and gravity-separation techniques to separate the hydrated lime, approximately 93 pct of the titanium was subsequently recovered as purified carbide containing 54 to 70 pct titanium with cao content as low as 0.6 pct. This combination of techniques can be used to separate more than .90 pct of the cao from the tic. Therefore, this carbiding procedure is a viable method for treating titaniferous materials, including perovskite, that contain more than 20 pct cao. Tests made in a static-bed reactor showed that for the reaction of tic with elemental chlorine to produce titanium tetrachloride (ticl4), a temperature of at least 940 deg. F is desirable to achieve a suitable extraction of titanium in a laboratory chlorination reactor. In fluidized-bed tests at 840 deg. F, 98 pct of the titanium contained in tic was extracted.
