effect of lead nitrate on cyanidation of gold ores

Effect of lead nitrate on cyanidation of gold ores: progress Oct 01, 2000 · In a cyanide solution, lead nitrate, lead sulphide and lead sulphite react with gold to form AuPb2, AuPb3and metallic lead, which clearly accelerate the gold dissolution. The nature of the sulphide minerals affects the formation of lead or lead alloys on the gold surface. G. Deschenes, R. Lastra, J.R. Brown, S. Jin, O. May, E. Ghali 63 2000Effect

The case of effect of lead nitrate on cyanidation of g ores

influence of lead nitrate on cyanide leaching of g and ovacik cyanidation plant leaching time, 24 hours for the constant 100 mg/h ore feed rate was applied as optimal for all lead nitrate tests. results showed the increase in g and silver recoveries between 0.41.2% for g and 3.911.6% for silver at the end of 24 hours leaching by the addition of lead nitrate as 0.10.5 kg/mg. influence of lead nitrate on cyanide leaching of g and hours leaching by the addition of lead nitrate as 0.10.5 kg/mg. nacn consumption decreased or did not change except for the ovacik ore. in the case of the ovacik ore it slightly increased. keywords: lead nitrate, g, silver, cyanide leaching introduction extraction of g from its ores by cyanide leaching has been the preferred method for control of lead nitrate addition in g recovery her deschênes effect of oxygen and lead nitrate on the cyanidation of a sulphide bearing g oreminerals engineering, great britain apr. 5, 1995, 8:8:923. kondos process optimization studies in g cyanidation, hydrometallurgythe netherlands, jun. 8, 1995, 39:235250. (pdf) effect of lead nitrate on cyanidation of g ores the effect of lead nitrate addition on the cyanidation of g ores has been studied (sayiner, 2014) and it is believed that the catalytic activity of lead on anodic dissolution of g consists on modeling of g cyanidationfigure 10 effect of ph on cyanide consumption (linget al., 1996).. 34 figure 11 the residual g concentration as a function of the ore particle size 35 figure 12 g dissolution rate for ore average particle size 30 and 177 m: (a) as a function of the dissolved oxygen concentration(b) as a function predicting cyanide consumption in g leaching: a kinetic the consumption of cyanide during processing operations is a major economic cost in the extraction of g from its ores, while the discharge of cyanide wastes may result in significant environmental pollution. many factors influence the levels of consumption and discharge of cyanide, including ore mineralogy and lixiviant solution chemistry. this paper proposes a robust methodology to effect of oxygen and lead nitrate on the cyanidation of a aug 01, 1995 · thus the combination of lead nitrate and oxygen are useful in reducing cyanide consumption but the reduction of g recovery is attributed to the fact that the g leaching rate is function of the ratio of cyanide and lead nitrate and the ph and the actual ratio is not optimized. g. deschênes, g. wallingford 22 1995g cyanidation lead nitrate can improve g leaching speed and quantity recovered, particularly in processing partially oxidized ores. effect of dissolved oxygen . oxygen is one of the reagents consumed during cyanidation, and a deficiency in dissolved oxygen slows leaching rate. air or pure oxygen gas can be purged through the pulp to maximize the dissolved cyanide g extraction process jxsc machinethe existing cyanide g plant in chinas g mines basically adopts two types of g extraction process, one is a socalled conventional cyanidation process for g extraction by continuous countercurrent washing with a thickener, and the g is replaced by zinc powder (ccd method and ccf).
