In gold recovery cyanide process, when the concentration of leaching cyanide is controlled at1500 mg / Lto 1800 mg / L, the cyanide concentration of noble liquid is 1000 mg / L to 1200 mg / L, and the pH value is about 10, which is good for zinc powder of gold replacement.[email protected]
The gold ore cyanide leaching pulp contains a certain amount ofFe2+,Cu2+,Zn2+,S2-, Fe3+ plasma, in addition to the metal sulfide mineral pyrite, pyrrhotite, chalcopyrite and sphalerite. The leaching process consumes a large amount of cyanide and dissolved oxygen, and reduces the cyanide leaching effect.Get Price
