Separation Arsenopyrite Effecting

Colloidal ZnCO3 as a Powerful Depressant of Arsenopyrite in

The effects of ZnSO4 on arsenopyrite depression were studied with sodium carbonate and sodium isobutyl xanthate (SIBX) as the pH regulator and collector, respectively. In both micro and real ore flotation tests, ZnSO4 showed better depression on arsenopyrite (pH 7.5–9.0 adjusted by Na2CO3) compared with sodium humate. The depression mechanism of ZnSO4 on arsenopyrite flotation was

Arsenopyrite from the ton-magnetic residue obtained after wet magnetic separation. The heavy mineral table, concentrate assayed 5.2 dwt gold/ton and represented a gold recovery of 3.3% with respect to. run-of-mine ore. Recovery of arsenopyrite by flbtation or tabling finally rejected a cyanidation residue assaying .1 to .14 dwt gold/ton.

Effect of dextrin on flotation separation and surface

The flotation separation of chalcopyrite and arsenopyrite was enabled by dextrin. The effect of dextrin on the surface properties of arsenopyrite is greater than on chalcopyrite. Dextrin adsorbed onto the arsenopyrite surface by both physical and chemical adsorption. arsenopyrite, chalcopyrite, dextrin, flotation, separation

the alkaline leaching system to be studied for arsenopyrite oxidation should be one that minimizes the harmful effect of iron oxide. Cyclic voltammetry and chronocoulometry can be used to determine the relative reaction rates of electronic con­ ductors, such as arsenopyrite, as a function of potential in various alkaline media.
