ABSTRACT: This study concerned the chlorination of ilmenite with hydrogen chlor-
ide, CC14 vapors, a mixture of C12 and CC14 vapors, or chlorine, actli.g on i1man-
ite and coal (2:1) at 400-700C. it was proven that relatively pure FeC13 and es-
sentially iron-free concentrates of Ti02 are obtained when ilmenite is exposed
to the effects of HCI at 600-700C. it was shown that 99.20-99.80% of T! and
99-16-99-75% of Fe are recovered in the form of the chlorides when ilmenite is
chlorinated with CC14 vapors, a mixture of C12 and CC14, or chlorine (on briquets)
at 600-700C. When the briquets are exposed to the effects of chlorine at 700C,
the reaction proceeds rapidlyduring Its Initial half hour the recovery of TiFe306
reaches 95%, while the remaining balance of the concentrate distills slowly. The

former; an additional transistor switch is connected betwee'n the':base and 06 second
lead.
