u-T TATES PRECIPITATION or cor-PER Guenther Hamprecht and Gustav Pauckner, Ludwigshafen-on-the-Rhine, Germany, assi to I. G. Farbenindustrle g'nors Aktiengesellschaft,

Application June 14, 1939, Serial No. 279,052. In Germany lune 29, 1938 w 1 Claim.
The present invention relates to improvements in the recovery of copper from its solutions by precipitation. p
' It' has already been proposed to precipitate 5 copper from its aqueoussolutions by means of base metals, as for example nickel. Commercial nickel is, however, relatively passive so that the precipitation requires very l0ns.,ec0nomica1ly insupportable times it it is desired to obtain solu-' l tions poor in copper. e
It has therefore been proposedto carry out the precipitation of the copper by nickel at temperatures of more than 100 (2., as for example at i from 160 to 180. C., and at correspondingly increased pressures.
We have now found that nickel which has beenprepared electrolytically. and which hasvnot been remeltedafter its electrolytical deposition is considerably more suitable forthe precipitation oi copper trom its solutions. When usins' such nickel it is not necessary to use either long times or temperatures above 100? C. in order to obtain 7 solutions poorincopper.
The iollowlnz example will the nature of this invention but the invention is not restricted to this example.
Example to 36 grams perliter and after 8 hours it amounts 10 toonly 1 gram per liter. It the precipitation be effected at 90 C. the copper content '8 hours is irom2to3'gramsperliter.
If on the'other hand pieces of sheet nickel which have been obtained by melting and rolling 15 nickel are used, the solution stillcontains 44 grams of copper perliter after 8 hours. v
what weclaimiszr y In the precipitation of comer by means of nickel the use or nickel which has been prepared electrolytically and which has not been remelted Y after its le'ctrolyflcal depos tion. q
