Anodic reaction mechanism of complicated antimony-lead concentrate in Slurry Electrolysis has been investigated by the anodic polarization curves determined under various conditions. The main reactions on the anode involve the oxidation of FeCln (2-n), with limited oxidation of jamesonite particles during the process. Through mineralogical studies and relevant tests, the mechanisms behind the leaching reactions of jamesonite and gudmundite during Slurry Electrolysis have been confirmed. The oxidation reaction of FeCl3 generated by the antimony-lead concentrate itself, along with non-oxidation and oxidation complex acid dissolution processes for jamesonite and gudmundite respectively, and the oxidation of air from stirring, contribute to achieving a leaching ratio of antimony up to about 35% when utilizing HCl-NH4Cl solution to leach the concentrate directly. The findings suggest that, given the theoretical electric quantity required to oxidize antimony in Slurry Electrolysis, all contained elements—antimony, lead, and iron—are leached from the antimony-lead concentrate.
