Thermodynamics and technology of extracting gold from low-grade gold ore in system of NH4Cl-NH3-H2O JU Shao-hua(巨少华), TANG Mo-tang(唐谟堂), YANG Sheng-hai(杨声海) School of Metallurgical Science...) is about -0.2 V; when the sum comes up to 0.5 mol/L, the value of φ(Au+/Au) increases to 0.2 V. In this case, φ(O2/OH-) is as high as 0.7 V. This means that it is feasible to extract gold in this system......

Influence of surfactants on bioleaching of arsenic-containing gold concentrateFANG Fang(方芳)1, 2, 3, ZHONG Hong(钟宏)1, 3, JIANG Fang-ming(江放明)1, 3, LI Zhao-hui(李朝辉)2, CHEN Yong-fa(陈永发)2, ZHAN Xue-hui... cycle of arsenic-containing gold concentrate, surfactants were used to promote the interaction between bacteria and ore to increase the arsenic leaching rate. Three different kinds of surfactants were......
