Extracting Ag from Residue Containing Silver with Na_2S_2O_3

Zhang Qin-Fa 1,2 ,Gong Zhu-Qing 1,Chen Bai-Zhen 1,Li Jing-Sheng 1 (1.Institute of Metallurgical Science & Engineering,Central South University,Changsha,Hunan 410083,China; 2.Zhuzhou Engineering College,Zhuzhou,Hunan 412008,China)  
It was investigated that Ag was extracted from residue containing 0 38% Ag by leaching with Na 2S 2O 3 and then reducing Ag with Na 2S 2O 4.The results showed that the rate of leaching was above 86%,the rate of reduction of Ag was above 95% when the dosage of Na 2S 2O 3 was 160 kg/t,dosage of NH 4OH 50 L/t,temperature of leaching was 60℃,time of leaching 3 hours.The solution after reduction of Ag may be used again for leaching.
