A new technigue for copper electrolysis of Au-Cu ore with chlorination leaching electrolyte in a diaphragm cell;

A new Au-Ag recovery process,"additives roasting-chlorination leaching-reduction by sodium sulfite" for the complex gold flotation concentrate is described in this article.

In the chlorination leaching solution of Shizhuyuan complex bismuth concentrate bearing beryllium and fluorine,there were more than forty species which were coordinated with metal ions,such as Bi 3+ ,Be 2+ ,Fe 3+ ,and ligands such as Cl -,F - and SO 2- 4,respectively.

The synthesis of sodium antimonate from antimony concentrates by chloridizing leaching-oxidation and hydrolysis decomposition-alkali synthesis process is investigated.
