The Unit of electrolysis  consists of 120 cells , Each cell contains 25 rows of anode and cathode sheets ,The Zinc  sulfate solution
flows  to  the  cathode  plate of   ZN 2 +   ,  decomposes and  Zinc  sheet   occurs  on  cathod  sheets  . The Zinc sheets  are  cut out . from cathode   plates  every   24  hours  and   after  weighing  are  delivered  to  melting  and  casting  unit .
