Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
135 words
A method of operating an electrolytic cell which comprises the following steps: (a) preparing an electrode by: (a 1 ) explosion bonding a titanium strip to a copper hanger bar to form an explosion bonded metallurgical junction between said titanium strip and copper hanger bar; and (a 2 ) fillet welding a titanium sheet to said titanium strip to form a fusion bond weld thereinbetween; (b) assembling an electrolytic cell comprising an anode and the electrode prepared according to step (a) as a cathode; (c) further providing an electrolytic solution in said cell comprising a salt of either respectively copper, gold, silver or manganese; (d) passing an electric current through the electrolytic solution provided in step (c) in said cell; and (e) recovering respective copper, gold, silver or manganese on the surface of the cathode.
Claim 2
Independent Claim
135 words
A method of operating an electrolytic cell which comprises the following steps: (a) preparing an electrode by: (a 1 ) explosion bonding a titanium strip to a copper hanger bar to form an explosion bonded metallurgical junction between said titanium strip and copper hanger bar; and (a 2 ) fillet welding a titanium sheet to said titanium strip to form a fusion bond weld thereinbetween; (b) assembling an electrolytic cell comprising an anode and the electrode prepared according to step (a) as a cathode; (c) further providing an electrolytic solution in said cell comprising a salt of either respectively copper, gold, silver or manganese; (d) passing an electric current through the electrolytic solution provided in step (c) in said cell; and (e) recovering respective copper, gold, silver or manganese on the surface of the cathode.
Claim 3
Dependent Claim
31 words
The method defined in claim 1, step (c), wherein the electrolytic solution comprises a salt of copper and wherein copper is recovered during step (e) on the surface of the cathode.
