PROCESS OF ELECTROLYTIC EXTRACTION OF METAL FROM SOLUTION CONTAINING ITS IONS AND GEAR FOR ITS IMPLEMENTATION Russian patent published in 1996 - IPC

FIELD: process of electrolytic extraction of metal from solution. SUBSTANCE: for electrolytic extraction of metal from solution containing its ions located in first cell metal is deposited by means of cathode on to endless belt partially submerged into solution conducting electric current, then it is again dissolved by means of anode in electrolyte of adjacent second cell with partial submersion of endless belt. Metal with high degree of purity solved in second cell is anew deposited at cathode. For implementation of process auxiliary electrode is manufactured in the form of endless U-shaped loop belt partially submerged into solution. In this case one loop is submerged into first cell, second one-into next one. As result of such arrangement auxiliary electrode implements in turn functions both of cathode and anode. EFFECT: enhanced efficiency of extraction of high-purity metal. 13 cl, 6 dwg, 2 tbl
