' nically called, a suliid the precious metal Specification of 1% Drawing.

" nuary 9.9, 1909.
Sclial N0. i065.
even ii I l 7 such metal is combined with, uhat 18 techcan be dissolved in solution carrying tree chlorin and a solution carrying an oxid of I nitrogen. l have foundthat the solution carrying tree chlorin is advantageously made i by electrolyzing a chlorid compound, such for instance as a chlorid of sodium, in an electrolytic apparatus with two comp-rtments. The chlorin is evolved in the posii tive compartmentand the anolyte oi? this apparatus may then be used for the purpose aforesaid. ,As to the oxid of nitrogen, l 1 have found that instead or using the anolyte oi? an electrolytic apparatus, the pro iuct of g the electric arc with the aid of which the nitrogen of the air is oxi lined-"can suh' stituted in such cases where large currents are attainable.
In the course of my experiment found that the oxirl of nitrogen, p x l with the aid of the electric are. is very rm- 1 stable and in analyzing the product it was found that the resultant gas contains rather appreciable amount of active or g r ozone, and when this gas was it l. nitr a liquid containing the concentrate of an orc carrying precious or other more s. the. centrate is more rapidly attacircd than it nitric acid per so would be substituted. The so rapidly ahsm'bed luv the liquid the same is heated to 2* lin de'u again accelerates the i In using tlrlS improved pro that it is best to first; place the concentrate in contact with the chlorinated water, that is, the anolyteot' the apparatus in which a chlorid compound was eletrtErolyzed, and then carrying the gas as it comes from the are and before it has time to decompose and also before it; has undergone the refrigerating process to make it stable, in contactwith the I chlorinated water, which greedily absorbs it.
l also found that it is best to agitate the coneentiute. After a lapse of a few h0ursdepending on the strength of the solution and nature of the ore-the liquid is drawn 5 oli and it will be found that the precious metal. formerly contained in the concentrate, new dissolved in the liquid.
Having now described my lILVBIItlOII,\Vl11Lt l claim as new and desire to secure by Letters Patent is:
l. The process of extracting metal from its ore, which consists in first subjecting the f concentrate oi said metal to a solution containing free chlorinand then subjecting the solution to the nitrous product of the electric are.
The process of extracting metal from its ore consisting in subjecting the ore to the dissolving action of a chlorinated Water and aggaswus product of the electric arc.
ll. 'llie process of extracting precious.
metal from its ore, consisting in subjecting said ore to the dissolving action of the anolytie product of a ehlorid compound and gaseous compound of nitrogen produced with the aid Oil the electric arc.
l. in the prom it extracting precious metals trom their ores, the improvenurnt, which consists in surcliarging the solution adapted to dissolve said metalwith the gaseous product of an electric are, said product containing an oxid of nitrogen in unstable condition.
l n testimony whereof l atlix my signature in presence of two witnesses. v
