Improvements in Preparing Briquettes of Ironstone Waste or Dust
or similar Ferruginous Materials for Smelting.
I, LOUIS ABRAHAM BRODE, of 5 St. Andrews Road Pollokshields, in the County of
Renfrew, North Britain, Enameller, do hereby declare the nature of this Invention to
be as follows, that is to say:-
My said Invention has for its object the utilising of ironstone waste or dust or
similar ferruginous materials by preparing in an improved manner, briquettes which
can be advantageously used in smelting furnaces.
In carrying out the Invention the ironstone waste or dust or other ferruginous
material is thoroughly mixed with what is known as Armenian bole and contains
silicated oxide of iron. This mixture is rendered adhesive by being mixed with a
liquor formed by boiling in water waste ground rice or other farinaceous waste
together with a little silicate of soda. A plastic mass is formed which is moulded
into briquettes which after being thoroughly dried can be smelted in ordinary blast
furnaces along with the ordinary ore.
Dated this Twenty-fifth day of February 1887.

or similar Ferruginous Materials for Smelting.
I, LOUIS ABRAHAM BRODE of 13 Stuart Street, Shawlands, in the county of Renfrew,
North Britain, Enameller 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 said Invention has for its object the utilizing of ironstone waste or dust or similar
ferruginous materials by preparing in an improved manner briquettes, which can be
advantageously used in smelting furnaces.
In carrying out the Invention the ironstone waste or dust or other ferruginous
material is thoroughly mixed with what is known as Armenian Bole, the name
commonly given to the refuse resulting from the distillation of alum shales, and which
contains silicated oxide of iron. This mixture is rendered adhesive by being mixed
with a liquor formed by boiling in water, waste ground rice or other farinaceous waste
together with a little silicate of soda. A plastic mass is formed which is moulded into
briquettes or blocks which after being thoroughly dried by pressing or in a stove can
be smelted in ordinary blast furnaces along with the ordinary ore.
In practicing my said Invention, I use Armenian Bole in the proportions of about
1 lb. by weight in the dry state to about 1 cwt. of iron dust or waste or iron sand.
The proportion of farinaceous matter used is abont 1 per cent. of the weight of iron
dust or waste or iron sand and the proportion of silicate of soda is about 1 oz. to the
said cwt. of iron sand.
It is here explained that the proportion of Armenian Bole as well as that of
farinaceous matter and silicate of soda necessarily varies with the character of the
iron-dust or waste or iron sand used in any particular case for as is well known iron
dusts and iron sands vary considerably in the per centage of iron they contain as well
as in the proportions of foreign or impure matter.
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 rendering of ironstone waste or dust or the natural sands of iron or analogous
ferrugineous materials capable of being smelted in blast furnaces by converting the
same into briquettes or blocks by the admixture therewith of Armenian Bole together
with farinaceous matter boiled in water and with silicate of soda whereby a plastic
mass is produced and converted into briquettes or blocks substantially as hereinbefore
described.
