PROVISIONAL SPECIFICATION.
Improvements in the Utilization of Certain Iron Residues.
CHARLES DREYFUS Chemical Manufacturer of Clayton, Manchester in the
County of Lancaster do hereby declare the nature of this invention to be as
follows:-
In the manufacture of aniline or naphtylamine or in all cases where an organic
nitro compound is reduced to an amido compound by means of iron borings or
turnings there is a residue composed of sothe iron & iron in its various degrees of
oxidation: this residue is in the form of a dirty slime which it was difficult to
utilise up to now. My invention consists in the utilisation of such iron residues and
is carried on as follows:-
I take the slimy residue & mix it by hand or by the ordinary machinery used
for brickmaking into a suitable consistency & make it in suitable moulds, into
bricks or other forms suitable for handling. These bricks are then dried in the
usual manner known for brickmaking, & they may also be burned in ordinary
brick kilns, if required. I then obtain in either form a rich iron ore suitable for
all purposes for which iron ore is used, such as puddling furnaces or for iron or steel
making. I can also mix a proportion of 2 to 10 parts of ordinary clay to every
100 parts of the slime reckoned as dry such admixture giving more adhesion to the
bricks or the blocks which I obtain.

COMPLETE SPECIFICATION.
Improvements in the Utilization of Certain Iron Residues.
I CHARLES DREYFUS, of Clayton near Manchester in the County of Lancaster
Chemist 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 :-
In the manufacture of aniline, or naphthylamine, and in all cases where an
organic nitro compound is reduced to an amido compound by means of divided iron
such as iron borings, or turnings, there is a residue composed of some iron and iron
in various degrees of oxidation, and constituting a dirty slime which hitherto it has
been difficult to utilize.
My invention has for its object the utilization of such iron residues, and consists
as follows:-
I take the said iron residue and mix it into a suitable consistency for making into
bricks blocks, or pieces. The said mixing may be done by hand, or by any
ordinary, or suitable, machinery, such, for example, as that used in brick making.
To bring the residue to the proper consistency for moulding, or forming into bricks,
blocks, or pieces, and to give proper adhesion, I may add water, or other liquid, as
required, and any suitable agglomerating material, such, for instance, as ordinary
clay, a suitable proportion of which, for example, is 2 to 10 parts, (by weight), to
every 100 parts of the residue reckoned as dry. I then make the mass into bricks,

example, by means of moulds such as are used for moulding bricks.
blocks, or pieces, so formed are then dried which may be done, for example, in the
manner in which bricks are dried, and they may be burned in ordinary brick kilns
if required. I thus obtain pieces of material rich in iron, and constituting,
practically iron-ore as it is suitable for all purposes for which iron ore is used;
such as, for instance, for treatment in puddling furnaces, or for iron, or steel,
making.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
The utilization of the aforesaid iron residues by mixing and moulding them to
form bricks, blocks, or pieces and drying, or drying and burning, the same, so that
they can be used in puddling furnaces, or otherwise in making iron, or steel,
so that the said residues are utilised substantially as hereinbefore explained.
