- Patented J 11119 Applieation flled March 10,1909. Serial in. 82,476.
- Asymmetrical currents are produced either i by commuting a direct current at small and unequal intervals of time, as for example, alternately every 1/50 and 3/50 seconds, or such currents may be produced by the simultaneous use of a direct current and an alternatin' current connected in parallel. I prefer owever, to produce the asymmetrical current ina still difl'erent way, to wit by connecting a source of direct current and a source of alternating current 1n series.
- the process can be used for the refining of gold still richer in silver; in fact, the use of the asymmetrical current in accordance with the present process permits of the purification of .all classes of gold which are encountered in actual practice.
- I current corresponding to from I In the electrolytic treatment of gold in" U accordance w'th the old process ereinbefore-referred to, the 'heating-ofthe bath is I a J1250*+1315 as5s 7o absolutely essential, as the direct current ,ampemgmo the 'uare meter, 1 :thisbwse; when alone?
- m coldl f the Volta e of the direct current component though b l reqmslte denslty of is about from 1 to 1.1 volts per bath and the mntffoo i 9 Square meter, ⁇ total voltage per'cell as indicatedfon a hot current component is not allowed to exceed ⁇ not more than l0 per cent, greater, is ad- P du preclpitatimn fZ' Q gold wire oltam'eter, is about 1.4 volts.
- the gold my a cold sohmon the use of volts as the maximum voltage of the direct etricalcurrentswhoseirect com o- V as mm P current, and 1 as 'the maxlmum voltage of -20 nenthas a density below 1000 amperes to'thethe alternating current p bath.
- the streng hs and Voltage of the currents bath and the direct ailment dynamo 1S employed may vary-widely accordin to the excited unt1l a polarized-direct current am characterof the n to b fin d g If th '30 meter inserted mthe circuit, indicates the 01d contains than 8 e t 6 v desired strength of the direct current.
- P Gen thedensityiof' the direct current component can be advantageously increased, or, if preferred, the strength of the alternating component relative to'the direct current com'ponent can be diminished.
- the ratio of the strength of t e alternating. current to I that of the directicurrent cannot be advan tageously diminished below a certain limit. For instance, if the strength of the alternating current becomes less than .707 of that of the direct current combined current will cease to be an alternating current' and wi become a mere undulatory direct current of eriodically varying strength, in which case, the peculiar advantages of-the combined Icurv rent hereinbefore set forth, are lost.
- gold is in the proportion of from L ⁇ to 2 per cent. ,being treated, which contains about 10 per of the solution, or the treatment can take cent. of silver, a density of the direct current place with a cold solution in which case 7 12! component of about 1250 amperes to the per cent.
- I may substithis desired strength of the direct current is represented by i and if it is desired to work with' a virtual intensity of the alternating 35 current represented by 6,, the Virtual inten- 4 sity of Y the total current obtained y the combined use of the two currents',can be calculated according to the formula i a/i 01,.
