Effect of hydrogen peroxide and lead(II) nitrate on gold cyanide leaching of Malaysian mesothermal deposit gold ore

Abstract: The gold extraction from Malaysian mesothermal lode gold ore through the cyanidation method was performed. The effect of hydrogen peroxide (H2O2) and lead nitrate Pb(NO3)2 were investigated on the percentage of gold recovery. The statistical analysis method using a response surface design-central composite design was applied to find the optimum condition for gold extraction. The studied parameters were NaCN concentration (300-500 ppm), H2O2 concentration (205-410 ppm), and Pb(NO3)2 concentration (50-150 ppm). … Show more

“…In addition, as a powerful oxidising agent, H 2 O 2 is widely used in the mining process [ 16 ]; it aids in synthesising various organic compounds [ 17 ] and works as an oxidant for constructing liquid-based fuel cells [ 18 ]. It is also employed in treating contaminated soils and wastewater, given its enrolment in Fenton’s reaction with the formation of the highly reactive hydroxyl radicals responsible for the aromatic and halogenated compounds’ withdrawal [ 19 , 20 ].…”
