EDWIN r. \VELGH, OF-DENVER, COLORADO.
PROCESS FOR TESTING QR REDUCING ORES.
Specification of Letters Patent. Patented April 27, 1909. Application filed Ju1y 30, 1908. Serial No. 446,164.
To all whom, it may concern:
Be it known that I, EDWIN P. \VELcH, citizen of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented certain new and useful Improvements in Processes for Testing or Reducing Ores; and I do hereby declare the following to be a full, clear, and exact descrip tion of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This inventiolprelates to a process for testing and reducing ores, and has for an object to provide a combination of certain reagents and the re-aetions thereof which reduces ores and properly separates the metallic therein found which can be identified in any usual well known manner.
A further object of the invention is to provide certain chemicals which, when mixed with powdered ore and ignited, reduces the ore to its metallic constituents.
iVith these and other objects in view, the
invention comprises certain novel constructions, combinations and arrangements of parts, as will be hereinafter fully described and claimed.
The present invention consists in mixing with powdered or potassium chlorate, a chemical which furnishes a considerable amount of oxygen, and a carbon, and then ignitin the mixed mass.
Preferably the potassium chlorate, twenty parts, wheat flour, thirteen parts, and .two parts of the argol are mixed and formed into a cake or tablet of any approved and desired form, shape and size. The remaining two parts of argol are then inclosed in a separate receptacle, and the two parts of sodium peroxid or its equivalent inclosedin another receptacle.
in use equal parts of' the argoym powdered form, the sodiunf croxid and] ore in powdered formed are iiiixed thorou hly and are placed upon the top of the/ca e or tablet above referred to and the whole ignited. For the purpose of proper combustion the cake or tablet is supported in any approved means whereby the air can properly come in contact with the ignited mass to supply oxygen thereto.
Instead of employing the sodium peroxid contained in the receptacle alone it is found desirable for many purposes to employ a mixture composed of seven parts of the sodium peroxid and one part of manganese dioxid, the reaction when ignited seeming to be accelerated by such addition. Therefore, as a s )ecific composition, for carrying into e'fl'ect-tlie present process a cake or tablet is employed composed as follows:
Potassium chlorate twenty parts, Wheat flour- -.thirfeen parts, Argo]; I f.wo parts.
in a separate re ':eptacle additional argol is stored. in still another separate. receptacle sodium peroxid or the mixture of sodium pcroxid and manganese dioxid is ltwi l be obvious that thereare a number of chemicals whlch Wlll respond to the requirements, but preferably potassium chlorate is employed in the proportion of twenty parts by weight, sodium peroxid, two parts by weight, and carbonaceous substance seventeen parts by weight. Instead of employing two parts of sodium peroxid a mixture of sodium peroxid, and manganese dioxid may be employed, preferably in the proportion of stored.
The ore to be tested is grouml to a fine powder and a small quantity mixed with equafparts of the argol and the sodium per- 'oxid mixture and placed upon the tablet and the whole ignited. After thorough seven parts of sodium peroxid and one part combustion the resultant mass is finely pow- -of manganese dioxid. The carbonaceous i dered and by examining with a glass the 100 45'substanccs employed are preferably wheat metallic particles canbe identified by their flour and argol in the proportion of thirteen color or may be panned and identified by parts by weight of wheat flour to four parts i any of the usual well known means. of the argol. v What claim is While the chemicals above referred to cm- I. The process of reducing ores consisting 105 50 ployed in the proportionsmentioned may be in mixing ore in a finely powdered form with mixed with the ore direct and ignited, it is material containing potassium chlorate and found that the mixture is dangerous for the sodium )eroxid, and carbon mutainingmateurpose of handling, transportatirn and the rial, and igniting the mass.- like, and for such purpose if pomfncreiiilly 2. The process of reducing ores consisting 110 employed in other proportions than those in mixing the ore in a finely powdered state above stated. f with material containing potassium chlorate,
smlinm peroxill. manganese ilioxiil argolfi wheat llour and igniting the mass.
3. The process of reducing ing in mixing the ore in a iinel POWLltIOtl state with a eoniposition eontaining potassium chlorate twenty parts, material rich in oxygen two parts, (illbfin eontaining material seventeen parts. aml igniting the mass.
t. The pr'oeess ol' Ittlllt'lllg ores eonsistore in a linely powdered state with a eomposition containing potasing; in mixing the sinin chlorate t\\'ent parts, SOtlllllll peroxid and manganese (lio.\'i l two parts, -arl)on eonlaining material seventeen parts.
5. The proeess of reducing ores consisting in mixing the ore in a linely powdered state with a (oinposfltion eontaining potasores consist- ,e on
\illlll chlorate twent parts, material rieh in 1 oxygen two parts, \rl ieat llonr thirteen parts,
argol four parts.
6. The process of reducing ores consisting in mixing the. ore in a finely powdered state with a eomposition containing potassium chlorate twenty parts sodium peroxid and manganese lio):i\l two parts, \rheat 'llonr thirteen parts, arg'ol four parts. aml igniting the mass.
In testimony whereof I have allixed my i signature in presence of two witnesses.
