JOSEPH BAXERES ALZUGARAY, 70, 71 Bishopsgate Street Within, Ethelburga
House, London, Engineer do hereby declare the nature of this invention to be as
follows:-
This invention relates to the reduction of antimony ores, & their like, & the
purification of metals obtained therefrom.
In order to reduce the ores & compounds of antimony, these are placed into
chambers, or clay retorts, or into any convenient receptacle of enamelled iron, or of
any suitable material.
These retorts or chambers are heated at a low temperature of from 6 to 800 degrees
centigrade, in a furnace which may be similar to a gas retort furnace, & a current
of coal, or petroleum gas, or any other kind of gas, or hydrogene is made to pass
through.
If the orc dealt with is a sulphide, the sulphur is separated, in the state of
sulphuretted hydrogene, & the sulphur is obtained by incomplete combustion.
The reduced antimony is collected in iron moulds or other convenient receptacle.
In order to purify or refine the metal thus obtained, & to separate the precious!
metals therefrom, it is used as anode in an electrolytic bath. The cathode of the
same being a plate of lead or other good conductor.
The bath is formed by a solution of chloride or other salt of antimony dissolved
in an alkaline or alkaline earth or metallic chloride, or in a mixture of the same
or in an acetate or a tartrate, or a mixture of either, acidified or not as may be.
required, either with hydrochloric acid or with any other acid.
Preferably dissolve the chloride of antimony in solutions of chlorides of sodium, .
potassium, or calcium.
The pure metal collected in the cathode, is melted & afterwards collected into
moulds &c.; The impurities are collected in the anode & the precious metals
separated therefrom.

1 JOSEPH BAXERES ALZUGARAY of 9, Quality Court Chancery Lane W.C.
a communication from abroad by Dr. Joseph Baxeres Torres of 7 Rue Laffitte
Paris, France, 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:
This invention relates to improvements in and connected with the reduction of
antimony ores, alloys and salts and purification of the metal obtained therefrom.
In carrying out my said invention to reduce the ores and compounds of antimony,
these are placed into chambers, clay or plumbago retorts, or into any convenient
receptacle of enamelled iron fire clay, plumbago, or of any suitable material.

page_text: These retorts or chambers are heated at a low temperature of from 6 to 800°
degrees centigrade, in a furnace, which may be similar to a gas retort furnace ;
and a current of coal, or petroleum gas, or of any other kind of gas or hydrogen is
made to pass through.
If the ore dealt with is a sulphide the sulphur is separated as sulphureted
hydrogen, from which the sulphur is afterwards recovered by incomplete combustiou
in a closed chamber.
The reduced antimony is collected in iron moulds or other convenient receptacle.
In order to purify or refine the metal thus obtained, and the precious metals
therefrom, it is used as an anode in an electrolytic bath. The cathode of the same
being a plate of lead or other good conductor.
This electrolytic bath is formed by a solution of chloride or other salt of
antimony dissolved in an alkaline or alkaline-earth or metallic chloride, or in a
mixture of the same or in an acetate or a tartrate, or a mixture of either, acidified
or not as may be required, either with hydrochloric acid or with any other acid.
Preferably dissolve the chloride of antimony in solutions of chloride of
sodium, potassium or calcium.
The pure metal collected in the cathode, is melted and run into moulds. The
impurities are collected in the anode and the precious metals separated there-
from.
The bath I prefer is a solution of chloride of antimony, obtained by dissolving
the antimony ores (sulphide of antimony in hydrochloric acid. To prepare this
solution one part of antimony ore (sulphide) is dissolved in four parts of hydro-
chloric acid heating at the same time. When the solution is complete it is filtered.
To 80 parts of this solution 20 parts of chloride of sodium saturated solution are
added, the bath is then ready for use.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
:-
1. The reduction and fusing of antimony ores, alloys and salts in closed vessels
heated at any temperature; by making to pass through the antimony ores or
compounds to be reduced and fused a current of hydrogen, coal gas, petroleum
gas or any other kind of gas or hydrogen.
2. The method herein before described to purify and refine the metal or its
alloys, by forming with it the anode of an electrolytic bath, using as an electrolyte,
one or a mixture of the solutions of the several salts or chemical compounds such
as the chlorides, or other salts of antimony, dissolved in an alkaline, alkaline
earth or metallic chloride or in an acetate or a tartrate or a mixture of the same,
acidified or not as may be required with an acid.
3. The herein described process as and for the purposes described.
