PROVISIONAL SPECIFICATION left by the said George Henry Blenkinsop
at the Office of the Commissioners of Patents on the 19th August 1882.
GEORGE HENRY BLENKINSOP of 17 Hanover Street Swansea in that part of the
United Kingdom called Wales THE UTILIZATION OF THE HEAT CONTAINED IN
SLAG OR OTHER SUBSTANCES WHILE IN A MOLTEN OR SEMI MOLTEN STATE FOR THE
PURPOSE OF CALCINING AGGLOMERATING SINTERING OR BINDING TOGETHER THE
MOLTEN OR SEMI MOLTEN SUBSTANCES WITH THE OTHER SUBSTANCES ADDED
WHEREBY THE AFTER TREATMENT OF THE COMBINED SUBSTANCES IS GREATLY
FACILITATED WHETHER THE AFTER TREATMENT RELATES TO THE EXTRACTION
PRODUCTION OR PURIFICATION OF THE METALS OR METALLIC PROPERTIES CONTAINED
IN SUCH COMBINED SUBSTANCES "
For the purpose of this invention I take the slag or other material while it is
being tapped or run off from the furnace reverberatory Blast or other description
of apparatus in a molten or semi molten state by preference in a thin stream and
with it mix lime or limestone by preference in small pieces or in a state of fine
division so that the slag or other material shall be perfectly and completely mixed
with the lime or limestone

page_text: In order to accomplish this I run the slag or other material into a suitable
vessel and at the same time cause the fine or broken lime or limestone to mingle
with the slag or other material so that the particles of lime or limestone may be
brought into contact with the slag or other material under treatment
By these means the heat contained in the slag or other material is utilized for
the purpose of converting the limestone into lime and for causing the lime to
combine with the silica and alumina contained in the slag or other material under
treatment and thus render easy the extraction of the iron contained in such slag
or other material.
Also by causing this mixture and amalgamation of the slag or other material
with the lime or limestone the line will readily combine with the sulphur
phosphorus and other deleterious matter contained in the product under treatment
and thus free the iron contained therein from such deleterious matter.
In order to utilize the slag or other material produced from smelting copper
silver gold lead zinc cobalt-Nickel or antimony and which slags have already
been allowed to cool. I first smelt such slags in a suitable furnace, by preference
in a blast furnace with an ore or material containing copper silver gold lend
cobalt nickel antimony or sulphur or any or all of these metals whereby the
metal or metals contained in such slag or other are profitably extracted and the
slag or other material brought into a suitable condition for carrying out the
invention
After the slag or other materials shall have been mixed with the lime or lime-
stone in the manner above described it is treated as an iron ore or product containing
iron by any of the known methods

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said George Henry Blenkinsop in the Great Seal Patent Office on the
6th February 1883.
GEORGE HENRY BLENKINSOP of 17 Hanover Street Swansea in that part of the
United Kingdom called Wales THE UTILIZATION OF THE HEAT CONTAINED IN
SLAG OR OTHER SUBSTANCES WHILE IN A MOLTEN OR SEMI MOLTEN STATE FOR THE
PURPOSE OF CALCINING AGGLOMERATING SINTERING OR BINDING TOGETHER THE
MOLTEN OR SEMI MOLTEN SUBSTANCES WITH THE OTHER SUBSTANCES ADDED
WHEREBY THE AFTER TREATMENT OF THE COMBINED SUBSTANCE IS GREATLY
FACILITATED WHETHER THE AFTER TREATMENT RELATES TO THE EXTRACTION
PRODUCTION OR PURIFICATION OF THE METALS OR METALLIC PROPERTIES CONTAINED
IN SUCH COMBINED SUBSTANCES
For the purpose of this invention I take the slag or other material while it is
being tapped or run off from the furnace reverberatory blast or other description of
apparatus in a molten or semi molten state by preference in a thin stream and
with it mix lime or limestone by preference in small pieces or in a state of fine
division so that the slag or other material shall be intimately mixed with the lime
or limestone.
In order to accomplish this I run the slag or other material in a thin stream into
a suitable vessel and at the same time cause the fine or broken lime or limestone
by preference limestone to mingle with the slag or other material so that the
particles of lime or limestone may be brought into intimate contact with the
particles of slag or other material under treatment
By this means the heat contained in the slag or other material is utilized for the
purpose of converting the limestone into lime and for causing the lime to agglomerate
with the slag or other material and thus render easy the extraction of the iron
contained in the slag or other material under treatment.
Also by causing this intimate mixture of the slag or other material and the lime
or limestone the lime will readily combine with the sulphur phosphorous and other
deleterious matters contained in the product under treatinent and thus free the iron
contained therein from-these deleterious agents.
In some cases it will be found advantageous to mix iron ore with the molten or
semi-molten slag or other material with or without the addition of limestone so
that the iron ore may be calcined and agglomerated with the slag or other
material
In order to utilize the slags or other material produced from copper silver gold
lead zinc cobalt nickel or antinony smelting which slags have already been
allowed to cool I first smelt these slags in a suitable furnace, by preference in a
blast furnace with an ore or material containing copper, silver gold lead cobalt
nickel antimony sulphur or any or all of these metals by which treatment the
metal or metals contained in the slag or other substances are profitably extracted
and the slag or other material brought into a suitable condition for carrying out
this my invention
This treatment of the slag or other material produced from copper silver gold
lead, cobalt nickel or antimony sinelting with an ore or other material containing
copper silver gold lead cobalt or nickel antimony or sulphur or all or any of
these metals is a well known and profitable operation.
After the slag or other material shall have been mixed with the lime or limestone
or iron ores in the manner described in this specification it is treated as an iron ore
or product containing iron by any of the known methods

page_text: On treating a silicate of iron with the addition of limestone by any of the
ordinary processes great difficulty is experienced (owing to the fusible nature of
the silicate of iron) in the reduction of the protoxide of iron to the metallic state.
In those cases in the treatment of various ores and metallic substances where
it is found advantageous to partially calcine and agglomerate the ores or metallic
substances under treatment I effect both these objects by causing the ores and
metallic substances to mingle with molten or semi molten slag or other substances
in the manner already described in this Specification.
I claim as novel in this my invention the addition of lime or limestone or iron
ore or other suitable material to slag or other products containing iron while the
said slag or other products are in a molten or semi molten state for the purpose of
extracting the iron contained therein and or for the purpose of purifying the same.
Also the utilization of the heat contained in molten or semi molten substances in
the manner described in this specification for the purpose of calcining agglomerating
or sintering together other substances whether in a state of fine division or other-
wise such mixture of substances being afterwards treated together for the extraction
or otherwise of the metal or metals contained therein. In witness whereof I the
said George Henry Blenkinsop have hereunto set my hand and seal. this Second
day of February One thousand eight hundred and eighty three.
Signed and sealed in the
presence of
