Description
, Miran Sra'rhs CHARLES ROBESON SQUIRE, OF BROOKLYN, NEW YORK, ASSIGNOR OF ONE HALF TO JAMES F. HOTGHKISS,
OF PLAINFIELD, NEW JERSEY.
PROCESS OF PREPARING ORES FOR AMALGAMATION AND DESULPHURIZING THE SAME.
SPECIFICATION forming part of Letters Patent No. 309,168, dated December 9, 1884.
Application filed July 21, 1883. Renewed August 2, 1884. (No specimens.)
1' 0 ctZZ whom it may concern.-
Be it known that 1, CHARLES RoBEsoN S UIRE, of the city, county, and State of New York, have invented certain new and useful Improvements in Processes of Preparing Ores Containing the Precious Metals for Amalgamation and Desulphurizing the Same, of which the following is a specification.
In carrying out my invention I use a solution of the residuum from the manufacture of nitric acid. This residuum is sometimes called niter-cake, and its analysis is substantially as follows: sulphate of soda, 75.90; free sulphuric acid, 16.61; water, 6.01; insoluble matter, 1.29. Total 99.81.
The strength of the solution must be determined by experience. I have with good effects used it of about 35 Baum, subject to variation, as occasion has required.
The solution is used upon ores that have been roasted as well as upon those that have not; and the process consists in immersing the orcs in a bath of niter-cake in solution, either alone or in the amalgamator containing the mercury. If the ore, either roasted or not, is immersed in the solution, either in a bath of said solution or in an amalgamator with mercury, the solution has a scouring effect upon the oxide of iron and gold, by means of which the iron is removed and the gold left free to be taken up by the mercury.
This action is partially chemical and partially due to the mechanical action of the pulverizer. It has been found that mercury cannot flour or float in amalgamating, either in this or any any other process, in the presence of the said solution.
This process applies to all ores carrying gold or silver. 7
One of the advantages presented by nitercake, when used in solution, is in the large amount of acid present, and the cheapness of the miter-cake as a refuse product of the manufacture of nitric acid, hitherto unused for this purpose, is to be considered.
I do not wish to restrict my invention to the use of the solution at any particular stage of the operation upon the ore, or any particular character of operation thereon, whether such operation involves the use of fire, steam, or any other agent, or Whether the solution is used with or without heat, or whether the ores are pulverized or not. Neither do I wish to confine my invention to the accomplishment of any one particular effect upon the ore or metals, as from what has been said hereinbefore its effects thereon when differently applied, or under different circumstances and conditions, are seen to be various-as to desulphurize the ores, prepare the metals for amalgamation, prevent the fiouring or sickening of the quicksilver, 8w.
1 am aware that ores have been reduced by calcination with sodic sulphate. Neither do I claim the use of a solution of salt-cake alone, as set forth in my application filed July 21, 1883, Serial No. 101,520, nor that of a solution of a mixture of salt-cake and miter-cake, as
set forth in my application filed April 10, 1883, Serial No. 91,305; but I am not aware that ore, whether roasted or not, has been desulphurized and prepared for amalgamation by exposure to the action of niter'cake maintained in a state of solution.
Having thus described my invention, I claim 1. The within-described process of preparing ores for amalgamation, which consists in subjecting the ore to a solution of niter-cake, substantially as herein set forth.
2. The within-described process of desulphurizing ores, which consists in subjecting them to a solution of niter-cake, substantially as hereinbefore set forth.
In testimony whereof I have hereunto set my hand and seal this 19th day of July, A. D. 1883.
