Show the story of garfield N V R g before blister copper goes to the refinery it Is subjected to several treala n e 0 f reduction at garfield here a stream of blister being 11 oln take the converters editors note mote I 1 this 1 Is the seventh anth ot of a serl ferlas of eight titled the story of ffield Oart eld in tills this article we go to the refinery but it is still the story of garfield as the latter plant produces so much of the copper that la Is refined in t the he united states cop copper per ling la Is an cl electrochemical ectro th pro process in which the crude copper I 1 Is cast into blocks called anodes and submerged in an add acid solution of copper sulphate anodes are spaced paced eight or ten inches apart in solution tanks 15 to 20 feet long and in between each two anodes la ii a th thin 1 8 sheet beet of pure copper called a start ng sheet E electrical current ente enters a the tank through the anode and passes asses through the solution and d to the starting sheet or cathode in doing this it takes the copper from the anode a and nd deposits it on the cathodes cath foreign material other than copper la Is not so transferred and eventually settles to the bottom ot of the tank as a slime the pure cathodes are then removed melted and cast into various shapes tor for final fabrication wire bars are made to be eventually drawn into copper wire ot of various sizes I shapes are produced to be used ii in making copper pipe and tubing ingots ingols are made to be used in the brass industry these various shapes produced at the refinery are the raw material for the fabricating industry all ot of them must be subjected to va varied ried and numerous manufacturing processes before the finished copper material la Is ready tor for the tha market ithe the eighth and an last ot of this series will DO be published later in these th columns |
