Gold extraction from natural sources, including gold rocks and gold ores, can be done by leaching the gold concentrate or crushed gold rocks, in a solution of hydrogen peroxide and hydrochloric acid Hydrogen peroxide is essential as a bleach in the textile industry and in processing used paper.
The final gold extraction rate (95% to 96%) is already reached after two to four hours when hydrogen peroxide is used. And, even more important, it is more than 10% higher than in the case of the aeration after the same time. The final extraction of the cyanide accessible gold was not reached before 48 hours when the simple aeration was used.

01-07-2017· Previous experience in other gold extraction plants indicated the possibility of the use of hydrogen peroxide (H 2 O 2) for the purpose of pre-oxidation. AngloGold Ashanti's Siguiri plant in Guinea introduced oxygen supplementation via H 2 O 2 injection in the cyanidation circuit, and that resulted in an improvement in overall plant gold recovery from ∼90% to ∼94% ( Verster, 2016 ).
Gold cyanidation using hydrogen peroxide - ScienceDirect. 01/04/1999 The effect of hydrogen peroxide concentration was determined by measuring the gold dissolution rate at 0.01 M NaCN, pH 10, 400 min −1, 25°C and H 2 O 2 concentrations in the range of 0.3–30 mM ().At low peroxide concentrations, the cyanidation rate increased with the initial hydrogen peroxide concentration, …
The effect of hydrogen peroxide on gold leaching rates in alkaline cyanide solution is a matter of controversy and debate. Early studies indicated that the reduction of hydrogen peroxide on gold surfaces is kinetically hindered, and the dissolution rate of gold in oxygen-free solutions containing hydrogen peroxide is very slow.
