The effect of lead nitrate addition on the cyanidation of gold ores has been studied (Sayiner, 2014) and it is believed that the catalytic activity of lead on anodic dissolution of gold consistsLive Chat

It means that lead nitrate addition should be a function of mineralogical composition of the ore (Deschenes et al., 2000 Deschenes and Prudhomme, 1997). In this paper, the effect of lead nitrate addition to the cyanidation of the Ovacik, Havran, Mastra Low Copper and Mastra High Copper gold ores was investigated and discussed. The OvacikLive Chat

This paper discusses some of the latest efforts to improve the understanding of the use of lead nitrate in cyanidation. The study is based on an electrochemical approach to establish the nature of the mechanisms related to gold, a surface analysis study, using Xray photoelectron spectroscopy (XPS), to determine the modifications on gold and sulphide minerals (pyrite, pyrrhotite andLive Chat
Effect of lead nitrate on cyanidation of gold ores: Effect of lead nitrate on cyanidation of gold ores 1267 It is interesting to note that when the gold electrode treated with lead sulfide was put in 1 M NaCN solution without lead nitrate addition, and the same potential sweep used in Figure 3 was performed, four peaks were obtained as shown in Figure 4. This curve has the same feature asLive Chat
This paper deals with the effect of the addition of lead nitrate and ultrafine grinding on the cyanidation of an antimonial refractory gold and silver ore. The results indicated that the recoveryLive Chat
