effect of lead nitrate on gold leaching

influence of lead nitrate on cyanide leaching of g and effect of lead nitrate addition on cyanidation of havran, ovack, mastra lcu (low copper) and mastra hcu (high copper) g ores was investigated by laboratory tests at the ovacik g mine metallurgy laboratory. leach tests were performed at optimum nacn additions and ph values while different lead nitrate additions were applied. effect of hydrogen peroxide and lead(ii) nitrate on g together on the g extraction from cyanidation process is . in this study, the effect of lead nitrate addition together with h 2o 2 on the cyanidation process and the reaction kinetic were investigated. 2. materials and methods 2.1. g ore the g ore used in this study was provided from a local g mine in peninsular malaysia. 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. leaching kinetics and mechanisms of surface reactions during jan 01, 2004 · a pretreatment with lead nitrate reduced the extent of g surface coating by ag, fe and s. stibnite, at a concentration as low as 20 ppm, significantly affected the g leaching kinetics through forming a passivating film of sb(v) oxide possibly sb2o5. the most practical way to alleviate the effect of stibnite is to leach the materials at a treatment of copperrich g ore by cyanide leaching concentration of reagents. in direct cyanide leaching tests, the effect of cyanide concentration in the range of 1.57.5 g/l nacn was studied. in the ammoniacal cyanide leaching tests, main and interaction effects of concentrations of sodium cyanide (0.52.5 g/l nacn), ammonia (02 mol/l nh3) and lead nitrate (01000 g/t effect of lead nitrate on cyanidation of g ores: progress the formation of a passive layer on g particles has a significant influence in the initial stages of leaching. the addition of lead nitrate notably decreased its inhibiting effect. g. deschenes, r. lastra, j.r. brown, s. jin, o. may, e. ghali 65 2000effect of lead nitrate concentration on g leaching how to effectively identify overdosing of lead nitrate [pb(no3)2] in g cyanidation.i 39;m interested in optimizing the lead nitrate addition at a standard 4000 tpd g mill using conventional cyanidation. we currently add 240g/t lead nitrate to try to maintain our 39;reducing power 39(ppm s
