Abstract: Taking the typical refractory high nickel copper anode slime as the raw material， the effects of temperature， time and liquidsolid ratio etc. factors on the removal of the metals selenium， copper and nickel were studied. The results showed that， after roastingleaching twice， 995% of selenium， 997% of copper， 9335% of nickel were removed. 9876% silver was in the leaching solution， and the amount of gold reached 1820g·t-1 from 193g·t-1. The best conditions of the first roastingleaching process were as follows， the roasting temperature of 650℃， the roasting time of 1h， m(H2SO4)/m(anode slime) of 12， the leaching temperature of 55℃， the leaching time of 1h， and the liquidsolid ratio of 6. The best conditions of the second roastingleaching process were as follows， the roasting temperature of 500℃， m(H2SO4)/m(anode slime) of 12， the roasting time of 3h， the leaching temperature of 55℃， the leaching time of 1h and the liquidsolid ratio of 6. The weight of the anode slime decreased to 1126% that of the original after the pretreatment， which greatly enhanced the handling capacity of the equipment during the subsequent recovery process.
