Method For Manufacturing High Purity Tin, Electrowinning Apparatus For High Purity Tin And High Purity Tin |
| 摘要 |
Provided is a method for manufacturing high purity tin including: depositing electrodeposited tin on the surface of a cathode 11 by electrowinning in an electrolytic bath in which a diaphragm 14 is placed between an anode 12 and the cathode 11, by using a raw material for tin as the anode 12 and a leachate obtained by electrolytically leaching the raw material for tin in a sulfuric acid solution as an electrolytic solution, the electrolytic solution containing a smoothing agent for improving a surface property of the electrodeposited tin; discharging the electrolytic solution from the electrolytic bath such that lead in the discharged electrolytic solution is removed; and putting the electrolytic solution from which lead is removed back into the electrolytic bath. |

1. A method for manufacturing high purity tin, the method comprising:
depositing electrodeposited tin on the surface of a cathode by electrowinning in an electrolytic bath in which a diaphragm is placed between an anode and the cathode, by using a raw material for tin as the anode and a leachate obtained by electrolytically leaching the raw material for tin in a sulfuric acid solution as an electrolytic solution, wherein the electrolytic solution contains a smoothing agent for improving a surface property of the electrodeposited tin, discharging the electrolytic solution from the electrolytic bath, removing lead from the discharged electrolytic solution, and putting the electrolytic solution from which lead is removed back into the electrolytic bath. |
