Complete Specification Left, 27th Feb., 1890-Accepted, 6th Sept., 1890
PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Ferro-aluminium.
I, CAMILLE ALPHONSE FAURE, of 15 Rue des Halles, Paris, France, do hereby
declare the nature of this invention to be as follows:-
My invention has for its object the production of ferro-aluminium by a series of
simple and economical chemico-metallurgical operations.
On to or over a mixture of bauxite and carbon at red heat I cause to pass a gas
rich in chlorine such as for instance, the perchloride of iron. The vapors and gases
resulting from this operation then pass over scraps or cuttings of iron at red heat,
the result being the formation of chloride of iron and ferro-aluminium.
The ferro-aluminium thus obtained is re-melted and "titrated." The chloride of
iron is condensed and collected in a crucible in which it is subjected, at a suitable
temperature, to a current of air, resulting in the formation of oxide of iron and
perchloride of iron in the state of vapor, which is utilized, as hereinabove mentioned,
to act upon the bauxite or alumina earth. In this way there is constituted a sort of
cycle allowing of a continuous operation.
Dated this Fifth day of December 1889.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Ferro-aluminium.
I, CAMILLE ALPHONSE FAURE, of 15 Rue des Halles, Paris, France, Engineer,
do hereby declare the nature of this invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:-
My invention has for its object the production of ferro-aluminium by a series of
simple and economical chemico-metallurgical operations.
On to or over a mixture of bauxite and carbon at red heat I cause to pass a gas
rich in chlorine such as for instance, the perchloride of iron. The vapors and gases
resulting from this operation then pass over scraps or cuttings of iron at red heat,
the result being the formation of chloride of iron and ferro-aluminium.
The ferro-aluminium thus obtained is titrated or analysed, & then re-melted in
accordance with the result of the analysis, to obtain the final & required products.
The chloride of iron is condensed and collected in a crucible in which it is subjected,
at a suitable temperature, to a current of air, resulting in the formation of oxide of
iron and perchloride of iron in the state of vapor, which is utilized, as hereinabove
mentioned, to act upon the bauxite or alumina earth. In this way there is constituted
a sort of cycle allowing of a continuous operation.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what 1
claim is :-
:-
1. Passing perchloride of iron or other metal in the state of vapor, on to or over
a mixture of aluminous earth and carbon at red heat for the purpose specified.
2. Passing vapors and gases, obtained by the operation referred to in the previous
claim, on to or over scraps or cuttings of iron or other suitable metal, for the purpose
specified.
3. The hereinbefore described process for obtaining ferro-aluminium the said

page_text: process consisting in passing a gas rich in chlorine on to or over a mixture of
bauxite and carbon at red heat, and then passing the gases and vapors from this
operation over scraps or cuttings of iron at red heat, and finally regenerating the
chloride of iron so obtained by a current of air.
Dated this 27th day of February 1890.
