Electrodialysis System for Electrodeposition of Gold from Non-Cyanide Solutions
2011
Tatjana Sadirbajeva

The process removal of gold(III) ions from hydrochloric solutions containing 0.01 mol/l HAuCl4 accompanied with metal electrodeposition from cathodic non-cyanide solutions is studied at galvanostatic electrodialysis. A possibility of gold(III) electrodeposition from 0.1 mol/l solutions of sulphuric, nitric, hydrochloric, perchloric acids and ammonia is demonstrated. The gold electrodeposits with good adhesion and of bright appearance are obtained in all studied systems. The effects of the main electrodialysis parameters as well as of the composition of the cathodic solution on the gold(III) transport and electrodeposition rate are determined
