To all whom it may concern Be it lmown that I, NOAK VICTOR Hrs!- Nn'rrn, a subject of the King of Norway, re-
siding at Christiania, Norway, have inventscribe a process of refining copper nickel matte. A. .nietallic copper nickel anode is electrolyzed in a bath of sulfate of nickel.
The cathode is surrounded by a filtering ha and the electrolyte is circulated from cat ode to anode through the said bag and then into a cementation tank where the copper absorbed from the anode is removed by cementation, whereupon the solution is again returned to the cathode side. However, even at its best the cementation is slow and costly and would be im racticable were it not that I have succee ed in devising means whereby the circulation in the plating tanks can be reduced very considerably and-the amount of solutionjto be cemented is correspondingly diminished. The cost of cementation is namely in this case almost in direct proportion to the volume of solution and not to the amount of copper. The filter separating anode from cathode is so open that when the volume of circulation is reduced below acertain limit the filtering takes'place only in that part of the filter that is nearest to the inlet fox-the fresh solution. When there is no filtering in the other arts of the filter difiusion sets in and ions 0 copper wander into the cathode compertinent, contaminating the nickel. If for instance the electrodes are two feet wide by three feet deep and if the solution is run in process. Said cc.

plate. If the flow of solution enters at the I bottom the difiusion and contamination takes place at the top. I have now found that by alternatingly entering the flow oi,-
solution at the top and bottom, I can make a great saving in the amount of solution necessary to keep the copper outside of the filter.
In the annexed drawing is shown an electrolytic cell ada ted for carryingout the is of a well known construction and need not here be described in its details. T
A designates the cathode coin artment, B the anode compartment, (3 and pipes entering the cathode compartment, the pipe 0 having its lower end at the top of said compartment. The tops of these pipes are formed as funnels E, F, and into these iunnels is supplied electrolyte throu h G, H, said pipes being connects 'w1th a main supply pi eK through a two-way cock 1. Theme is now alternately set in one or thelotherposition and the nickel sulfate solution accordingly will be led alternatel to the i e C or to the i eD.
Wiiat I claim? is:-- p e In the process of separating copper -.from
