| Abstract: | The tbeory and technology for the purification of gold electrolyte by ether extraction are studied. The gold electrolyte containing Au 180 g/l,Ag 0. 5 g/l,HCl 210 g/l,Pt 9. 4o0g/l,Pd 10. 25 g/l and other base metal elements is diluted. By two-stage extraction and retro -extraction,the electrolyte is obtained containing Au 153 g/l,Ag 0. 0025 g/l,HCl 180 g/l,trace platinum elements and other base metal elements.The gold with its fineness greater than 99. 99% is produced in electrolytic refining under the condition of anede Au content>90%. The practice shows good reproduction. |
