Co-intensification of cyanide leaching gold by mercury ions and oxidant LI Qian(李 骞), JIANG Tao(姜 涛), YANG Yong-bin(杨永斌), LI Guang-hui(李光辉), GUO Yu-feng(郭宇峰), QIU Guan-zhou(邱冠周) School... be obtained and gold leaching rate is considerably increased on cyanide leaching of gold from gold concentrates. Key words: co-intensification; cyanide leaching; mercury ions; hydrogen peroxide......

minerals will greatly affect the leaching of gold [9-11]. For example, in oxygen-enriched cyanide solutions, the presence of chalcopyrite was found to decrease the leaching rate of gold [12, 13... cyanide and oxygen in interaction with gold. As a result, the leaching rate of gold is lowered. In addition, the dissolution of copper sulfide produces a certain amount of sulfide ions [16]. These sulfide......

and discussion 3.1 Fundamental cyanide leaching characteristics Fundamental leaching characteristics of these three kinds of gold containing materials were studied though conventional cyanide leaching... as 48 h. Therefore, sulphide gold concentrate A was a typical refractory gold concentrate which is difficult to be effectively leached by conventional cyanide leaching. In contrast, sulphide gold......
is necessary to determine the optimum conditions for modeling of gold leaching in cyanide media. Many researchers studied on dissolution and modeling of gold ores cyanidation [1-8]. Artificial neural network... with the experimental results, as shown in Fig.6. It is indicated that model of ANN exactly reflects the correlation between the input and output layers. The function of gold cyanide leaching parameters......
Trans. Nonferrous Met. Soc. China 25(2015) 597-607 Treatment of copper-rich gold ore by cyanide leaching, ammonia pretreatment and ammoniacal cyanide leaching A. D. BAS, E. KOC, Y. E. YAZICI, H... September 2014 Abstract: The treatment of a copper sulphide-bearing gold ore by direct cyanide leaching, ammonia pretreatment and ammoniacal cyanide leaching was investigated. Dissolution behaviour of gold......
