desorption electrolysis system in ethiopia

Gold Ore Desorption Electrolysis And Electrowinning . Rapid: The temperature of desorption electrowinning can reach as high as 150 generally 30~55 higher than in another kind system and the working pressure of system can reach as high as 0.5Mpagenerally 0.2~0.5Mpa higher than in another kind system so the desorption electrowinning is rapid with 12 hours typically 50 ~60 time shortened.
