Gentleman do hereby declare the nature of said Invention for "IMPROVEMENTS
IN OBTAINING COPPER to be as follows:

1
This Invention relates to the separation and to the obtaining of copper when
existing in solution either in natural or in artificial products such for example as
in what are known as copper waters, or mine waters in which copper is contained
in a soluble form and also when it is contained in artificial or manufactured
products such for example as in the solutions resulting from and obtained in the
extraction or separation of copper from ores or from metallurgical products or
alloys and consists in effecting the precipitation of the copper from its solution by
the employment of Iron in a divided condition either as reduced Iron or as Iron
Turnings, or as Iron Filings, or as Iron borings, and maintaining the same together
with the cupreous solution in agitation and contact in order that the precipitation
and separation of the copper may be readily effected and thus economize both Time
and Plant.
In carrying out my Invention I add to the solution or solutions containing
copper Iron in a divided condition either as Reduced Iron, or as Iron Filings, or as
Iron Turnings or as Iron borings, and maintain the same in agitation and in
contact with the solution containing copper, oither by means of the Injection of
steam or of air or by mechanical means or otherwise in order that the precipitation
and separation of the copper may be readily effected and thus economise both
Time and Plant.
In carrying out this Invention I thus cause the cupreous solution to be intimately
mixed with any of the before mentioned forms of divided Iron in order that tho
copper existing in solution may be precipitated therefrom. This precipitation may
be effected either at the ordinary temperature or at an elevated temperature. The
precipitated copper thus resulting is allowed to subside and is soparated from the
solution either by filtration or decantation and the copper thus obtained may be
treated by any of the well known processes so as to render it of Commercial Valuo.

Gentleman do hereby declare the nature of my invention for "IMPROVEMENTS.
IN OBTAINING COPPER" and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:—
My Invention relates to the separation and to the obtaining of copper when
existing in solution either in natural or in artificial products such for example as
in what are known as copper waters or mine waters in which copper is contained
in a soluble form and also when it is contained in solution in artificial or manu-
factured products such for example as in the solutions resulting from and obtained
in the extraction or separation of copper from ores or from metallurgical products
or alloys and consists in effecting the precipitation of the copper from its solution
by the employment of Iron in a divided condition either as reduced iron or as
Iron Turnings, or as iron Filings or as iron borings or as scrap iron and maintaining
the same together with the cupreous solution in agitation and contact in order that
the precipitation and separation of the copper may be readily effected and thus
economise both time and plant.
In carrying out my Invention I add to or cause to come in contact with the
solution or solutions containing copper and contained in a suitable vessel or
apparatus Iron in a divided condition, either as reduced iron or as iron Filings, or
as Iron Turnings or as Iron borings, or as scrap iron, or other form of divided iron
and maintain the saine in agitation and in contact with the solution containing
copper, either by means of the Injection of Steam or of air or by mechanical means
or otherwise in order that the precipitation and separation of the copper may be
readily effected, I thus cause the cuproous solution to be intimately mixed with
any of the before mentioned forms of divided iron in order that the copper existing
in solution may be precipitated therefrom. This precipitation may be effected
either at the ordinary temperature or at an elevated temperature. The precipitated
copper thus resulting is allowed to subside and is separated from the solution either
by filtration or decantation or the precipitated copper may be removed from the
inferior portion of the vessel or apparatus and the copper thus obtained may be
treated by any of the well known processes so as to render it of Commercial
value.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I wish it to bo
understood that I make no claim to the employment of iron generally for effecting
the precipitation of copper from solutions but what I do claim is :-
Effecting the precipitation of copper from solutions by the employment of Iron
in a divided condition and in conjunction with agitation substantially in the
manner herein before described.
