for Smelting or Reducing.
I, JOHN MCCULLOCH, of Calderbank Iron Works, Airdrie, in the County of
Lanark, North Britain, Manager, do hereby declare the nature of my said invention
for "IMPROVEMENTS IN PREPARING ORES, OXIDES, OR COMPOUNDS OF IRON FOR
SMELTING, OR REDUCING" to be as follows, that is to say :-
My said Invention has for its object to facilitate the smelting or reducing of
ores, oxides, or compounds of iron, of kinds which have hitherto offered certain
difficulties; and my Invention is applicable for preparing what is known as "blue
billy" and is a residue obtained in copper works, also for preparing hematite and
other ores or compounds containing peroxide of iron.
In carrying out my Invention I pulverise and thoroughly dry the ore, oxide, or
compound of iron and mix it with coke, coal, or other suitable carbon, in the
proportion of about one equivalent of carbon for each equivalent of iron. I also
mix in carbonate of lime or other suitable fluxing material if necessary, and I add
as much pitch or other suitable substance as is required for agglutinating the
materials together. The compound so formed I mould into bricks or blocks with
very strong pressure obtained by means of hydraulic apparatus; and: I put the
pressed bricks or blocks in a smelting or other furnace either alone or along with
the materials ordinarily supplied to such furnace.

for Smelting or Reducing.
I, JOHN MCULLOCH, of Calderbank Iron Works, Airdrie, in the County of
Lanark, North Britain, Manager, 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, that is to say :-
My said Invention has for its object to facilitate the smelting or reducing of ores,
oxides, or compounds of iron, of kinds which have hitherto offered certain
difficulties; and my Invention, is applicable for preparing what is known as "blue
billy" and is a residue obtained in copper works, also for preparing hematite and
other ores or compounds containing peroxide of iron.
In carrying out my Invention I pulverise and thoroughly dry the ore, oxide, or
compound of iron and mix it with coke, coal, or other suitable carbon, in the
proportion of about one equivalent of carbon for from one to three equivalents of
iron. I also mix in dry carbonate of lime or other suitable fluxing material if
necessary, and I add as much pitch or other suitable substance as is required for
agglutinating the materials together. The compound so formed I mould into
bricks or blocks with very strong pressure obtained by means of hydraulic
apparatus; and I put the pressed bricks or blocks in a smelting or other furnace
either alone or along with the materials ordinarily supplied to such furnace.
For forming the mixed materials into blocks I use apparatus of the kind
described in the Specification accompanying my application for Letters Patent
N° 9591 of 1885; and I take special care to have the materials in a very dry
condition when combining them.
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 pulverising and thorough drying of ores, oxides or compounds of iron,
mixing the same with coke, coal or other suitable carbon, and with carbonate of
lime and pitch or other suitable agglutinating material, and moulding the compound
under great pressure with hydraulic apparatus, for the purpose of smelting or
reducing the iron substantially as hereinbefore described.
