I, ASTLEY PASTON PRICE, of Margate, in the County of Kent, Chemist,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
THE TREATMENT OF CERTAIN ZINC ORES AND COMPOUNDS OF ZINC, AND IN THE
MANUFACTURE OF ZINC AND OXIDE OF ZINC," to be as follows:-
My improvements consist in the mixing of certain ores of zinc, calcined
ores, or oxides or carbonates of zinc, or metallic zinc, when in a state of
division, either with or without the application of heat, with bituminous coal,
or with coal or carbonaceous matter and bituminous coal, or with coal or
carbonaceous matter and pitch, tar, asphalte, or bitumen, or with pitch, tar,
asphalte, or bitumen, or other bituminous material, such materials when not
in a fluid state, being, by preference, employed in a state of division, and
subjecting such mixtures to pressure for the purpose of binding and solidifying

page_text: the same, such pressure being applied with or without the previous application
of heat. The said materials after pressure may be subjected to a heating,
distillatory, or coking process, either in a suitable distillatory apparatus or in
any suitable coking oven or apparatus.
My improvements further consist in the admixture of suitable fluxes with
the before mentioned materials or any of them, and subjecting them to the
modes of treatment herein-before described, or to either of such modes.
The improvements further consist in the employment of all such pressed
and pressed and coked or carbonized materials, cither combined with suitable
fluxes, as before mentioned, or in conjunction with suitable fluxes for the
distillation of zinc, either in the distilling pots, or retorts, or distillatory
apparatus usually employed, or in any other suitable distilling apparatus, and
for the smelting or distillation of zinc, either in a blast, cupola, or other
suitable smelting or distilling furnaces, for the purpose of extracting the zinc
or oxide of zinc therefrom.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Astley Paston Price in the Great Seal Patent Office on the
22nd November 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I; ASTLEY
PASTON PRICE, of Margate, in the County of Kent, Chemist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-second day of May, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, tho
said Astley Paston Price, Her special license that I, the said Astley Paston
Price, my executors, administrators, and assigns, or such others as I, the said
Astley Paston Price, my executors, administrators, or assigns, should at any
time agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make, use, excr-
cise, and vend, within the United Kingdom of Great Britain and Ireland, the g
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN THE
TREATMENT OF CERTAIN ZINC ORES AND COMPOUNDS OF ZINC, AND IN THE MANU-
FACTURE OF ZINC AND OXIDE OF ZINC," upon the condition (amongst others) that
I, the said Astley Paston-Price, by an instrument in writing under my hand
and seal, should particularly describe 'and: ascertain the nature of the said
Invention, and in what manner the sanie was to be performed, and cause, tho.

page_text: same to be filed in the Great Seal Patent Office within six calendar months
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Astley Paston Price, do hereby declare
the nature of my said Invention, and in what manner the sanie is to be
performed, to be particularly described and ascertained in and by the following
statement, that is to say:-
My improvements in the manufacture of zinc relate to the preparation and
treatment of calcined or oxidized ores of zinc, and of artificially prepared
oxides of zinc, and are more particularly applicable to such calcined ores, or
to such artificially prepared oxides of zinc when the same occur or are
obtained in a fine state of division. When certain ores of zine, such as
blendes or sulphurets of zinc, are employed in order to obtain metallic zinc
therefrom by the methods now generally adopted, it is necessary to reduce
such ores to a minute state of division previously to submitting them to
calcination, in order that that operation may be facilitated, and that the more
complete and perfect oxidation of the ore may be effected. The calcined ore.
in such minute state of division is not well adapted for employment in a blast,.
cupola, or other similar furnace for the purpose of obtaining metallic zinc or.
oxide of zine. In order to render more advantageous the employment of such
calcined ores of zinc, or of artificially prepared oxides of zinc, for the purpose
of obtaining metallic zinc, I proceed as follows:-I reduce the ore, if neces-
sary, to a fine state of division, and subject such reduced ore to a process of
calcination or oxidation in the ordinary caleining furnaces or otherwise, as is.
well understood; I then mix or incorporate, with or without the application of.
heat, certain calcined ores of zinc, such as calcined blendes, carbonates or oxides
of zinc, or oxides of zinc when artificially obtained or prepared, or metallic zine
by preference in a fine state of division, with bituminous coal, or with coal or
carbonaceous matter and bituminous coal, or with coal or carbonaceous matter
and pitch, tar, asphalte, or bitumen, or with pitch, tar, asphalte, or bitumen,
or other bituminous matter or material or mixtures thereof, such materials.
when not in a fluid state being, by preference, employed in a state of division,
and subject such mixtures to pressure in suitable apparatus, as is well under-
stood and employed in the preparation and consolidation of fuel, in order that.
the materials or any of the mixtures before mentioned may be consolidated
and solidified; such operation of compression may be performed either with or
without the previous application of heat, or with application of heat during
such compressing operations. The said materials after having been submitted
to compression may be subjected to a heating, distillatory, or to a coking
process in any suitable heating, distillatory, or coking apparatus, in order that

page_text: a coked or a partially coked material may be obtained, or the pressed material
may be directly employed for the purposes berein-after mentioned.
My improvements further consist in the admixture of suitable fluxes with
the before-mentioned calcined ores of zinc or artificially prepared oxide of zinc
or compounds of zinc, together with the before-mentioned carbonaceous or
bituminous, tarry, or pitchy materials, in manner as aforesaid, which after
having been subjected to pressure or compression, either with or without the
previous application of heat, or with the employment of heat during such
compressing operations, may be subjected as before mentioned to a heating,
coking, or distillatory process, in order that a coked or a partially coked
material may be obtained, or the consolidated and pressed materials may be
employed direct for the purposes herein-after mentioned.
The proportions in which the materials may be mixed vary considerably
with the nature of the carbonaceous and bituminous or binding character of
the adjuncts employed, the admixtures and proportions of the carbonaceous,
bituminous, pitchy, and other binding materials to be mixed with the calcined
ores of zinc, or with artificially prepared oxides of zinc or metallic zinc, being
such that after having been mixed and incorporated, either with or without
the application of heat, by preference with such application, and after having
been submitted to pressure, the consolidated mass shall be in such a state as
to permit of its being directly employed for the purposes hereafter mentioned,
or of sufficient solidity and consistency to admit of its being submitted to a
coking, heating, or distillatory operation or process, and that such resulting
coked or partially coked material shall possess sufficient solidity or consistency
to be advantageously employed for the purposes and in the manner herein-after s
mentioned.
My improvements further consist in the employment, if necessary with the
addition of fuel, of all such pressed, or pressed and coked, or partially coked or
carbonized materials, either combined with suitable fluxes as before mentioned
or in conjunction with suitable fluxes for the distillation of zinc, either in the
distilling pots or in the distillatory apparatus generally employed or capable of
being employed for such distillation, and for the smelting or distillation and
obtaining of zinc or of oxide of zinc, in any suitably arranged blast, cupola,
or other similar furnaces, for the purposes of obtaining metallic zinc or oxide
of zinc.
Having now described and particularly ascertained the nature of the said
Invention, and the manner in which the same is or may be used or carried
into effect, hereby declare that what I consider novel and original, and there-
fore claim as the Invention secured to me by the herein-before in part recited

page_text: Letters Patent, is the preparation and treatment of zinc ores, after having
been submitted to a process of calcination or oxidation, and the preparation
and treatment of artificially prepared oxides of zinc or of metallic zinc, in the
manner and for the purpose herein-before described.
In witness whereof, I, the said Astley Paston Price, have hereunto set
my hand and seal, this Twentieth day of November, One thousand
eight hundred and fifty-eight.
ASTLEY PASTON PRICE. (L.S.)
